Billie Eilish is one of the easiest musicians to dress up as, because her looks are built on proportion and hair color rather than on one expensive garment. Most of the outfits below start with clothes cut far bigger than your size, a wig with a colored crown or a single bold shade, and a pile of silver jewelry. The rest borrow from her red-carpet years: a peach tulle gown, a white tweed suit, black lace. When I put one of these together, I sort the pieces into three piles first: what's already in the closet, what a thrift shop will have in the men's section, and the one thing worth buying new, which is almost always the wig. Here are the thirty I'd point a fan toward, from a ten-minute hoodie look to a full gown project.
Colored Roots on a Wig, Not Your Own Hair
Half of these costumes hinge on a two-tone wig: green, red or blue at the crown with black lengths. You can buy one ready made, but I usually make my own from a plain black synthetic wig, because the color sits where I want it and it costs less than you'd think. Synthetic fiber won't take ordinary hair dye, so this is a surface job.
- Put the wig on a foam head or a tall jar and brush it out with a wide-tooth comb.
- Wrap the lengths in a plastic bag or kitchen film just below where the color should stop, roughly two to three inches down from the parting.
- Mist temporary colored hair spray in light passes from about a hand's width away, letting each coat dry before the next. Heavy coats go crunchy and flake onto your shoulders.
- Brush the edge of the color gently downward with an old toothbrush so the line looks grown out rather than painted.
- Set it overnight before wearing, then lightly mist a light hold hairspray on top to cut down on transfer.
If you'd rather not spray anything, clip-in colored pieces hidden under the top layer give a similar effect and come out in seconds. On your own hair, a washable color spray works for one night, but it rubs onto collars, pillows and white jerseys, so keep it away from the pale outfits further down this list. Light and platinum hair can pick up a tint from bright sprays and hold it for a wash or two, so test a hidden strand first.
1. Billie Eilish Green Roots Streetwear Costume
If you only make one Billie costume, make this one, because the green-on-black roots read from across a room before anyone sees the rest. I'd buy a black wig and color only the top two inches with a temporary neon-green spray, holding the can close and sweeping it outward so the line stays soft. A black graphic tee that hangs near the knees, loose basketball shorts or wide cargo pants, a few silver chains with chunky rings and small rectangular sunglasses carry the rest. Keep the face pale with brushed-up brows and a little dark liner. Bright socks with chunky black-and-green sneakers finish it, and a toy microphone or a neon-green cup makes an easy prop. Everything here is loose, so you can dance in it for hours.
2. Billie Eilish Red Roots Jersey Costume
The red-and-black era needs almost no makeup skill, which is why I suggest it to people who dread the mirror part. Layer a roomy red basketball or hockey jersey over a long black tee, then add extra-long black shorts, tall white athletic socks and red-and-black sneakers. The red crown on a black wig is the whole costume, so use washable spray or clip-in pieces and never permanent dye on a wig fiber that won't take it. A backward cap, silver chains, stacked rings and sporty sunglasses do the rest. Leave the skin natural with defined brows and a smudge of black liner. A toy microphone or a handmade concert pass on a lanyard gives your hands something to do in photos.
3. Billie Eilish Blue Hair Silver Chain Costume
Early blue-hair Billie is a skater look, so it should feel lived in rather than styled. Wear an oversized black hoodie or graphic sweatshirt with loose black cargo pants, then add a silver chain, several rings, a wallet chain and narrow silver sunglasses. The cobalt wig matters most. Pick one cut around the shoulders, part it down the center and rough it up with your fingers, because perfect curls make it look like a store costume. Pale foundation, brushed brows and a cool gray shadow under the eyes keep the face right. Black high-tops and a small notebook covered in blue and silver stickers round it out. On a cold night this is my first pick, since a thermal fits under that hoodie without changing the shape at all.
4. Billie Eilish Neon Green Monochrome Costume
Head-to-toe neon only works if the greens match, and that's harder than it sounds. Lime fabrics vary wildly between brands, so I'd lay the sweatshirt and the baggy pants or long shorts side by side in daylight before committing. If they clash, switch to black bottoms with green graphics and let the top and wig carry the color. Put a neon-green wig into loose space buns, one of her playful early styles, and add white wraparound sunglasses, thick chains, big rings and fluorescent socks. Chunky white or lime sneakers keep the color running to the floor. Makeup stays fresh: black mascara and a thin line of green shadow. A green toy microphone is the obvious prop.
5. Billie Eilish Bad Guy Yellow Streetwear Costume
The yellow "Bad Guy" look is the one I hand to complete beginners, because the color does nearly all the explaining. An oversized mustard hoodie with matching relaxed pants is ideal; if you can't find a set, yellow track pants with a similar tee is close enough, and nobody checks the dye lot. Add a black or dark-blue wig with straight, slightly messy texture, then pile on chunky necklaces, rings and small tinted sunglasses. A matte complexion and softly defined eyes keep the face simple. White crew socks and thick white sneakers are comfortable for walking. For a prop, a toy microphone works, though a lightweight blue clock cut from painted cardboard is the detail fans will recognize from the video.
6. Billie Eilish Bad Guy White And Blue Costume
This second "Bad Guy" option is the family-friendly one. A loose white button-down over a plain white tee, bright cobalt pants with a roomy leg and a dark wig with blue undertones, worn straight and a little tousled, give you the shape. I skip the graphic face effects from the video entirely and use soft blue shadow instead, which keeps it suitable for school events and small kids at the door. Silver chains, small hoops and a few oversized rings handle the jewelry. White sneakers with blue socks tie the colors together. A blue-painted cardboard clock is the clearest prop. Nearly everything here comes from an ordinary closet or a single thrift trip.
7. Billie Eilish Bellyache Yellow Rain Suit Costume
"Bellyache" is the most approachable of her video costumes because the rule is simple: everything yellow. A yellow rain jacket with matching loose pants is the base; roll the cuffs if they're long, which also copies the video. Put a yellow or orange tee underneath so you still look coordinated once the jacket comes off indoors, because rain gear gets hot fast at a party. Choose a pale silver-gray wig or temporary gray spray, straight with a middle part, and add red-tinted sunglasses, a small chain and several rings. Mustard socks with white or beige sneakers finish it. Skip the bulky luggage and use a light yellow backpack with removable patches; it carries your phone and keys too.
8. Billie Eilish When The Party’s Over White Costume
The "When the Party's Over" costume is all about the black tear lines, so practice them before the night. The clothes are easy: a loose white tee, relaxed white pants and clean white sneakers for one unbroken column of white. Add a long silver-gray wig with a center part, plus silver chains and rings. For the tears, I use water-based face paint with a fine brush, starting just below the lower lashes and keeping well away from the waterline. Test the paint on the inside of your wrist the day before, because some people react to black pigment. A light dusting of setting powder stops the lines sliding on a warm night. Carry a clear reusable cup stuffed with black tissue paper, and keep a white jacket nearby for outdoors.
9. Billie Eilish Bury A Friend Black And White Costume
"Bury a Friend" has a dark mood that's easy to overdo, so I keep it to atmosphere and leave out anything that looks like an injury. Wear a roomy white tee over black bike shorts or loose athletic shorts, with an oversized black jacket you can shed indoors. A dark-blue wig, straight and messy, sets the era, and cool gray shadow gives a tired finish. If you want something more theatrical, draw a couple of clean vertical black lines beneath the eyes rather than fake wounds. Silver chains, chunky rings, black crew socks and heavy black sneakers complete the clothes. A small battery lantern is a safe prop that hints at the video and lights your way between houses.
10. Billie Eilish Therefore I Am Mall Costume
Want something that looks almost like regular clothes but still points to one specific video? The mall outfit from "Therefore I Am" is it. An oversized neutral tee or sweatshirt, loose knee-length shorts and an open cardigan or jacket make the base. Give a black wig green-tinted roots and keep the lengths straight and messy. Layered chains, chunky rings and small rectangular sunglasses that push up onto the head indoors handle the accessories. White crew socks and neutral sneakers are good for a long night on your feet. An empty paper snack bag is a funny, weightless prop. The baggy proportion is the whole point, so if your wardrobe runs fitted, shop the men's or plus-size racks two or three sizes up.
11. Billie Eilish NDA Black Road Costume
An all-black outfit is easy to assemble and easy to make boring. For the "NDA" look, wear an oversized black zip-up jacket over a long black tee with wide-leg trousers or baggy cargo pants, then add a shoulder-length black wig with a center part. Narrow sunglasses, stacked silver rings and two or three chains give the accessory mix. The trick I rely on is mixing textures, so nylon, cotton and faux leather sit next to each other and the outfit doesn't flatten into one dark shape in photos. Smoky gray shadow along the lash line stays wearable. Black socks with chunky sneakers or stable platform boots finish it. A small LED light or reflective armband nods to the road scene and makes you easier to see outside.
12. Billie Eilish Happier Than Ever Blonde Cardigan Costume
The early "Happier Than Ever" mood is the gentlest Billie costume on this list. An oversized cream cardigan over a neutral blouse or light knit, with a black knee-length skirt or loose black trousers, gives you the shape. A platinum wig in smooth shoulder-length layers with curled ends is what makes it read as her, so spend your money there. Peach blush, neutral lips and thin black liner keep the face soft. Add pearl earrings, a delicate necklace, black loafers or Mary Janes with white ankle socks, and a lightweight cardboard telephone receiver as the prop. A compact umbrella is a second reference, and it earns its place on a wet October night.
13. Billie Eilish Your Power Desert Costume
"Your Power" suits anyone who wants a loose, natural costume with no sharp edges. A flowing beige maxi dress works, as does an oversized tan shirt with matching wide-leg pants. Hold the fabric up to a window before you buy, because pale lightweight cottons can turn sheer under party lighting. A long platinum wig in relaxed waves, warm neutral shadow, brushed brows and nude lipstick finish the face. I'd swap the usual chains for a simple gold pendant and thin rings here. Beige ankle boots beat sandals in fall weather and stay within the earthy palette. A small dried-flower bouquet is the prop, and a cream shawl adds warmth without changing the look. It adapts easily to any size or level of coverage.
14. Billie Eilish What Was I Made For Yellow Dress Costume
The "What Was I Made For?" look depends on a fitted waist, so try the dress on and check the belt position before anything else. Choose a modest knee-length yellow dress with short sleeves and a softly flared skirt, adding a thin yellow belt if the waist needs definition. Style a black wig into a high retro ponytail with curled ends and neat side-swept bangs. Soft pink lipstick, winged liner and flushed cheeks give the mid-century face. Pearl earrings, sheer neutral tights and low yellow or cream pumps finish it. The prop is what tells people which video you mean: in it she sits at a table sorting tiny versions of her old outfits, so a miniature cardboard clothing rack or folding table does more than any accessory.
15. Billie Eilish Grammy Vintage Doll Costume
Her doll-inspired Grammy performance outfit is a second yellow costume, and the separates are what keep it from blurring into the dress above. Wear a lemon-yellow cardigan over a patterned blouse with a knee-length green pencil skirt, a narrow belt and a light scarf tied around the hair for a 1960s touch. The look was based on a 1965 doll ensemble, so everything should look tidy and slightly stiff. A black wig in a smooth high ponytail with curled ends, delicate liner, rosy cheeks and a soft pink lip handle hair and face. Pearl earrings, neutral tights and low black pumps you can actually stand in finish it. A small white poodle plush or vintage-style handbag is the prop.
16. Billie Eilish Pink Varsity Jacket Costume
This is the 2024 Grammy red-carpet look: a long white button-down, loose black trousers, a black tie and a roomy black varsity jacket with pale-pink satin sleeves. You don't need a replica. I'd buy a plain black varsity jacket and add pink felt hearts with fabric glue or a few stitches, because felt pressed onto shiny satin tends to peel once you start moving your arms. Give black hair a red crown and keep the lengths straight. Square black glasses, rings and silver chains handle accessories, with white socks and heavy black loafers or chunky sneakers on your feet. The tie, glasses and big shoes do as much as the jacket, so don't drop them.
17. Billie Eilish 2024 Oscars Schoolgirl Costume
Billie's tailored 2024 Oscars outfit is the one I suggest for office costume days, because it's essentially smart workwear. An oversized black blazer over a white ruffle-front blouse, plus a black-and-white tweed midi skirt at the knee or lower, gives you the base. A long black wig in a smooth blowout, narrow glasses and a plain black handbag come next. The white crew socks with black cap-toe Mary Janes are the detail people pick out, so don't swap them for tights. Natural makeup with softly lined eyes and muted pink lips keeps it polished. A cardboard music-note trophy sprayed gold is a fun prop, and a light one is easier to hold all evening.
18. Billie Eilish 2020 Oscars White Tweed Costume
A roomy white suit leaves space for warm layers underneath, which makes this 2020 Oscars look practical as well as sharp. An oversized white or ivory blazer with matching wide-leg pants is ideal; a textured cream suit is a fine stand-in if tweed won't turn up. Wear a black wig with neon-green roots, straight and shoulder length, then add pale rectangular sunglasses, silver chains, several rings and long neutral press-on nails. Soft matte makeup with defined brows and a hint of smoky liner keeps it calm. White socks and chunky white sneakers replace formal heels. A word of warning about white: it shows every drink spill and makeup smudge, so I keep a stain pen in a pocket and put the wig on after the face is done.
19. Billie Eilish 2020 Grammys Green Suit Costume
The green-and-black 2020 Grammy look is for anyone who enjoys a proper DIY project. Start with a loose black button-down and matching wide-leg pants, then add lime-green symbols or shapes yourself. Removable fabric stickers are quickest, but felt appliqués last longer; on a cotton shirt, a thin line of fabric glue around each edge stops the corners lifting after a few hours. An oversized jacket goes on top. A black wig with bright green roots, pale green sunglasses and long press-on nails painted in black-and-green finish the details, with several chains and big rings. Black-and-green sneakers and white socks keep you comfortable. Leave the makeup neutral so the print and hair hold the attention.
20. Billie Eilish 2021 Met Gala Peach Gown Costume
Her 2021 Met Gala Old Hollywood gown is the costume for someone ready to trade sneakers for tulle. Look for a peach, champagne or pale-beige ball gown with a fitted bodice and soft tulle layers. Floor length looks best, but tea length is far easier at a crowded party, and I'd choose it if there are stairs or a dance floor involved. A short platinum wig set in big curls swept back from the face is non-negotiable, since the curls are half the reference. Peach lipstick, winged liner and luminous skin come next, along with sparkling studs, a delicate bracelet and elbow gloves if you like them. Nude low heels or embellished flats and a small beaded bag finish it; skip any bulky prop.
21. Billie Eilish 2022 Met Gala Corseted Gown Costume
Her 2022 Met Gala gown was made from upcycled materials, which makes it the best fit on this list for a thrift-store build. A cream or pale-green floor-length dress with a structured bodice and a draped skirt is the goal; a fitted vest over a flowing blouse and maxi skirt gets you close for much less. A bustle effect is easy to fake: gather a length of thrifted curtain fabric and pin it at the back waist. Add sheer ivory sleeves or fingerless lace gloves, then style a black wig into a loose updo with strands left around the face. Rosy cheeks, taupe shadow and berry lipstick suit it. Cream ankle boots with a low heel stay hidden and comfortable. A folding fan or satin pouch is enough of a prop.
22. Billie Eilish 2023 Met Gala Black Lace Costume
The black 2023 Met Gala look is gothic without being costumey. Wear a long black dress with lace panels, sheer sleeves or ribbon detail, and check the lining in a bright room, because thin lace over an unlined body shows more than you'd expect under a camera flash. A structured corset-style belt over the top defines the waist. Part a black wig in the center and tie long braids or loose sections with thin black ribbon. Smoky charcoal shadow, a subtle wing and deep rose lipstick handle the makeup, with silver rings and a simple choker. Black platforms or low boots make the length manageable. A small black lace fan is the prop, and it sits well against all that dark fabric.
23. Billie Eilish 2022 Oscars Black Ruffle Gown Costume
You don't need a designer copy to suggest her black 2022 Oscars gown, just volume. A floor-length black dress with tiered ruffles or a wide sculptural skirt works, and so does a plain maxi dress with two or three black tulle overskirts stacked on top. Tulle flattens in a bag, so I hang it up the night before and fluff the layers with a cool hairdryer. Pair it with a short black wig with side-swept bangs or a neat bob, clean understated makeup, small silver earrings and chunky rings. Flats or low platforms vanish under the hem. A gold-painted cardboard award or a small evening bag is the prop. This one belongs at an indoor party; it's hard to walk a sidewalk in that much skirt.
24. Billie Eilish No Time To Die Black Sequin Costume
The "No Time to Die" era is all about restraint. A loose black blouse with subtle sparkle and matching wide-leg trousers, or an oversized black sequin suit, gives you the base, with a long black coat for outdoors. Sequins scratch the inside of your arms and catch on knit wigs, so I look for pieces with a soft lining before buying. Style a black wig in glossy shoulder-length waves with a center part. Charcoal liner, softly sculpted cheeks and a nude lip keep the face cinematic but quiet. Add silver drop earrings, rings and a thin necklace, with black pointed loafers or low ankle boots. A toy microphone or a folded sheet of handwritten music is the prop; leave the spy gear and toy guns at home.
25. Billie Eilish Blue Jersey Tour Costume
Her recent tour wardrobe is the most comfortable costume here for a long night. An oversized royal-blue sports jersey over a long-sleeve tee, extra-long denim shorts, white football socks and chunky sneakers give you the stage outfit. Wear a straight black wig under a backward blue cap or dark beanie, which also holds a cheap wig in place better than any pins. Silver chains, a pendant and rings layer over the jersey, and the makeup stays natural with cool liner and brushed brows. Soft knee pads over the socks are the stagewear clue; try them on and walk around first, because a tight strap behind the knee becomes miserable after an hour. A toy microphone and a handmade backstage pass finish it.
26. Billie Eilish Red Cap Layered Tour Costume
This red-cap look layers sporty pieces in a way that's easy to thrift. Start with a long white tee, add a loose black-and-white striped jersey over it, then baggy black shorts that hang below the knee. White crew socks, black knee pads and thick black sneakers come next. Tuck a black wig loosely under a backward red baseball cap and add square glasses, chains, a pendant and lots of rings. A little smudged liner keeps the face stage-ready without effort. A toy microphone or a homemade tour pass on a black lanyard is the prop. Because it's all athletic wear, you can dance, chase kids between houses or sit on the porch handing out candy without fussing with anything.
27. Billie Eilish Lunch Striped Jersey Costume
The "Lunch" era striped jersey is playful and easy to wear to school or a relaxed office party. Pull an oversized red, black and white sports top over a plain thermal shirt, then add loose black jorts or cargo shorts. Keep it roomy; a jersey that fits you normally won't read as Billie. A straight black wig under a backward cap, with narrow sunglasses resting on the brim, handles the head. Layered necklaces, chunky rings and a chain clipped to a belt loop come next. Clip that chain firmly, because a loose wallet chain swings into door handles all night. White athletic socks and black-and-red sneakers finish it, with a bright lunch bag covered in music-note patches as the joke prop.
28. Billie Eilish Chihiro Navy Streetwear Costume
"Chihiro" calls for one color in several shades, which is how you keep a navy outfit from looking flat. Wear a large navy zip-up jacket over an oversized blue-gray tee, with dark indigo cargo pants or knee-length shorts. I'd mix at least three blues so the layers separate in photos. A black wig with a few subtle blue clip-in streaks, worn tousled, keeps it moody. Silver chains, rings and dark rectangular glasses bring in her heavy accessory habit. Cool blue-gray shadow and clear balm on the lips suit the palette. Navy socks with chunky white-and-blue sneakers come last. Reflective tape on the jacket hem is worth adding if you'll be walking after dark.
29. Billie Eilish Birds Of A Feather Yellow Sweater Costume
The "Birds of a Feather" look trades streetwear for a soft, preppy take on her proportions. A big butter-yellow sweater vest over a roomy white button-down, with baggy khaki shorts or dark wide-leg trousers, gives the shape. Part a straight black wig in the middle and leave it slightly messy, then add a patterned tie, square glasses, rings and a silver pendant. White crew socks with brown loafers or chunky sneakers keep the academic feel. Soft brown liner and peach blush finish the face. For the song reference, glue two craft feathers to a small notebook rather than wearing real feathers, which shed on everything and irritate some people's skin.
30. Billie Eilish Lovely Black Outfit Costume
The final costume draws on the icy-haired "Lovely" era, and it's simple enough for anyone. A long black coat over a loose black top and wide-leg black pants should make one clean column, so pick fabrics that drape rather than stiff ones that bunch. Choose an icy silver-blue wig, straight with a center part and some volume around the face. Delicate silver chains and thick silver rings stand out against all that black. Cool gray shadow, black liner, pale blush and neutral lips handle the makeup, with black platform boots or chunky sneakers underneath. A clear umbrella is my pick for the prop, since it's light and useful, though a see-through box built from craft plastic is closer to the video.
How Big Should the Baggy Pieces Be?
Most failed Billie costumes are simply clothes that fit. Her streetwear works because tees hang near the knee, shorts finish below it and jackets swallow the shoulders. In practice that means shopping two or three sizes up, and usually in the men's section, where tees run longer and jerseys run wider.
What I check on the rack
- The shoulder seam should drop a few inches past your own shoulder, not sit on it.
- A tee or jersey should cover most of your shorts when you stand straight.
- Shorts should end at or below the knee, with a drawstring or belt so the extra waist doesn't slide down while you walk.
- Sleeves can be long; push them up rather than buying a smaller size.
Kids and smaller adults look especially sharp in this silhouette, but the extra fabric needs managing. I tie a knot in the side of an oversized tee if it hangs past mid-thigh on a child, and I roll long shorts once at the hem so they don't catch on stairs or bike pedals. For the gowns and suits, the rule flips: those need a decent fit at the waist and shoulders, so if you only have time to alter one piece, alter the formal one.
Start With the Hair, Then Build Outward
Billie gives you more range than most music costumes: neon streetwear, tour jerseys with long shorts, yellow rain gear, white separates, vintage dresses, peach tulle, black lace and big tailored suits. Whichever one you pick, the same four things make it read as her. The clothes need to be big, the hair needs the right color in the right place, the jewelry needs to be layered, and the shoes need to be chunky. Temporary color and thrift-store clothing keep the cost down. If you're stuck, start with the hair and build outward, and choose the version you can still move comfortably in at the end of the night.
