When I dress someone in a size 20, the first complaint is rarely about style. It's about clothes that stop cooperating by lunchtime: a waistband that rolls, a neckline that slides, a hem that rides up. That's the test I used for every look below. What follows are 35 plus size outfit ideas size 20 wearers can put on and then forget about, from summer maxi dresses to winter puffers. Each one starts with the piece that has to fit properly, usually at the waist or bust, before shoes and bags come into it, and I've noted where a cut tends to go wrong and who should skip it.
Reading a Size Chart When You Wear a 20
Size 20 isn't one measurement. In many brands it falls in 2X, but some put 20 at the top of 1X and others at the start of 3X, so I never order by the label alone. I measure three places with a soft tape: the fullest part of the bust, the natural waist (the narrowest point, usually just above the belly button) and the fullest part of the hips and seat. Then I compare each number to that brand's chart, not to the size I bought last time.
When your three measurements land in different sizes, buy for the part that's hardest to alter. Tops and dresses get bought for the bust and shoulders; trousers and skirts for the hips. A tailor can take a waist in easily, but there's rarely enough seam allowance to let one out.
- Woven fabrics with no stretch: buy to your real measurement plus a little ease, because they won't give.
- Ponte and other firm knits: the chart is usually reliable.
- Stretch denim: it relaxes with wear, so a snug first try is normal.
- Trousers: check the inseam, since many plus ranges come in petite, regular and tall lengths.
1. Plus Size Maxi Dress Outfit
Lightweight cotton or chiffon keeps a maxi from clinging in heat, and I check one thing before anything else: whether the waist seam sits at your real waist or an inch above it. A wrap bodice with a V-neck gives the clearest shape. Thin rayon can grab at the hip and stomach, so I hold the skirt up to the light; if I can see through it, it will cling too. Flat strappy sandals, a wide-brim straw hat, a woven crossbody and small gold hoops finish it. Bold florals or soft pastels both suit this dress, so go with whichever one brightens your skin rather than whichever is trending.
2. Size 20 High Waisted Shorts Outfit
High-waisted shorts define the waist and balance the leg, but the inseam matters more than the rise. I look for a five to seven inch inseam in denim or a linen blend with a little stretch, because shorter cuts ride up when you walk and longer ones can end at the widest point of the thigh. Tuck in a sleeveless blouse or ribbed tank, then throw an open linen button-down over it as a light jacket. Espadrilles or clean white sneakers, big sunglasses, a pendant and a canvas tote take it to a picnic or a sightseeing afternoon.
3. Plus Size Off Shoulder Top and Palazzo Pants
Smocked or elasticized off-shoulder tops are the only ones I trust at this size. A plain neckline band slides down the arm by noon and you spend the day tugging it back. The bare collarbone frames the face, and the volume of crepe or chiffon palazzo pants below keeps the outfit from feeling top-heavy. Have the palazzos hemmed for the wedge sandals you'll actually wear, since a dragging hem is the most common mistake I see with wide legs. One structured clutch and a cuff bracelet are plenty. Jewel tones, or a single color head to toe, carry it from a daytime event into dinner.
4. Plus Size Summer Jumpsuit Outfit
The measurement I check first on any jumpsuit is torso length, shoulder to crotch. If it's short, the whole thing pulls every time you sit, and that's the reason most people give up on jumpsuits. Once that fits, a surplice or V-neck bodice with a belted waist does the shaping, and wide legs in a cotton-linen blend or soft rayon balance the hips on hot days. Cork wedges or block-heel mules, a denim jacket tied at the waist and a canvas bucket bag keep it casual enough for a Friday at the office or a weekend outing.
5. Plus Size Cropped Jeans and Blouse Outfit
A cropped straight leg that ends just above the ankle bone shows the narrowest part of the leg, which is why I prefer it to a crop that stops mid-calf. Medium wash with some stretch, then a breezy blouse with a small puff sleeve or tie-neck that skims the midsection. I do a loose front tuck only; a full tuck in a soft blouse puffs out over the waistband. Pointed flats or low block-heel sandals continue the leg line, and a belt that matches the shoes keeps the eye moving down. A watch and a structured satchel make it work for a relaxed office.
6. Plus Size Wrap Dress Outfit
The wrap closure is adjustable, and that's why I reach for it so often: you set the tie at your narrowest point and the skirt skims the hips and thighs. My one warning is the neckline. On a fuller bust a true wrap can gape when you lean forward, so I check it sitting down and fix the overlap with fashion tape or a tiny safety pin inside. Pick jersey or silky crepe at knee or midi length, in a small floral or dot print. Nude pointed pumps or low wedges, a layered necklace that follows the V and a slim clutch keep it right for a bridal shower or daytime wedding.
7. Size 20 Sweater Dress and Knee High Boots
A sweater dress without a defined waist reads like a long jumper at this size, so I want shaping from seams or a self-tie belt. Ribbed and cable knits both work once that's there. I keep the hem at or just above the knee so wide-calf knee-high boots meet it with only a small gap, and opaque tights fill the gap on cold days. Camel or burgundy pairs easily with suede or leather boots in a matching shade, and a long pendant draws the eye down the center. If you'll wear a fitted wool coat over it, choose a fine rib; a heavy cable adds bulk under a coat.
8. Plus Size Puffer Jacket and Skinny Jeans
A puffer jacket looks bulky at size 20 mostly when the quilting runs in wide horizontal channels and the hem stops at the widest point of the hip. I look for narrower channels, a belted or shaped waist, or a cropped length that ends at the high hip. Dark stretch skinny jeans keep the bottom half slim against all that volume. Underneath goes a thin turtleneck, not a sweater; the down is already doing the insulating. Lace-up snow boots or waterproof heeled booties, a knit beanie, touchscreen gloves and a crossbody worn over the coat get you through winter errands and travel days.
9. Plus Size Faux Leather Leggings Outfit
Faux leather leggings look modern when the finish is matte or a soft sheen. High shine shows every ripple at the thigh. I choose a high rise with a wide waistband that won't roll, then cover the hip with a tunic-length sweater or a long button-down, and add a longline cardigan or boyfriend blazer as a third piece for one long vertical line. They don't breathe the way cotton does, so I keep them for cool days. Pointed ankle boots or sock boots, a chain-strap bag and simple hoops, then swap in a bolder earring for dinner.
10. Plus Size Midi Skirt and Chunky Sweater
Chunky knit over a floaty skirt is a texture contrast I like a lot, but the tuck decides whether it works. A thick fisherman sweater rarely stays tucked, so I front-tuck only the center few inches and add a thin belt to hold it. The skirt should be satin, pleated or printed and fall to mid-calf, moving away from the body as you walk. Low stacked-heel ankle boots meet that hem without cutting the leg in two, and fine gold necklaces over the knit add contrast. It suits a casual office day or a weekend brunch.
11. Plus Size Tailored Blazer and Trousers
This is the suit I'd build first for a size 20 work wardrobe. A single-button blazer with stretch, nipped slightly at the waist, sits better than a double-breasted one, which puts two rows of buttons across the widest part of the torso. Matching straight or gently flared trousers in navy or charcoal make one unbroken line. Shoulders are the one fit point a tailor can't easily fix, so I buy the jacket for the shoulder and have the waist taken in. Put a silky camisole or thin turtleneck underneath, then pointed pumps or loafers, a leather tote and a plain watch for meetings and presentations.
12. Plus Size Denim Jacket and Sundress
I pick a stretch denim jacket here, because rigid denim at size 20 binds across the back when you reach forward. It should end at the hip, or be slightly cropped, so the sundress waist still shows. Smocked bodices and shirtdress styles with a tie belt pair well, and the stiffness of denim against soft cotton keeps the dress from looking too sweet. White leather sneakers or flat sandals, a straw crossbody and simple studs. It's my answer for spring days when the forecast keeps changing its mind.
13. Plus Size Floral Midi Dress Outfit
Print scale matters more than color in a floral midi. Medium blooms on a dark or neutral ground are the easiest to wear, while tiny ditsy prints can look busy over a large area of fabric and huge blooms can land in awkward places. A shirred back or side tie defines the waist, and the hem should fall somewhere between knee and ankle. I pull the sandal color straight from the print and use block heels if there's grass involved, then add a rattan bag and pearl or bead drop earrings for baby showers, garden parties and spring weddings.
14. Size 20 Bodycon Dress with Structured Blazer
A bodycon dress stands or falls on fabric weight. Thin stretch jersey shows every seam underneath, so I look for a bodycon midi dress in a thick double knit that smooths and holds. Black, chocolate or forest green makes the strongest base. The single-button blazer stays open so its two front edges draw vertical lines over the dress, and pushing the sleeves up a little stops it looking like office wear. Pointed pumps or heeled ankle boots, a metallic clutch and a bold earring for a cocktail party or an evening work event.
15. Plus Size Wide Leg Trousers and Fitted Top
Wide-leg trousers need a fitted top or the outfit goes shapeless, and by fitted I mean close at the waist, not tight everywhere. Crepe or a soft suiting blend falls straight from the hip; stiff cotton twill tends to tent out. Tuck in a ribbed tank, bodysuit or slim turtleneck. Platform loafers or heeled clogs give lift and keep the hem off the ground, and I always set the hem length with those shoes on. A thin belt in the shoe color, a shoulder bag and small gold pieces finish it for a creative office or dinner with friends.
16. Plus Size Linen Matching Set Outfit
Linen sets are my summer pick for size 20 because the fabric stands away from the body instead of clinging, and air moves through it. Expect creases; linen wrinkles within an hour of sitting, and that's simply how it looks. If that bothers you, a linen-viscose blend creases less. Pair a relaxed button-down with high-waisted wide-leg trousers or pull-on shorts in sand or sage. Flat leather sandals or woven mules, a big straw tote, fine chains and tortoiseshell sunglasses take it from a resort to a city lunch without changing a thing.
17. Plus Size Maxi Skirt and Tank Top Outfit
Two pieces and very little thinking: that's the appeal. A high-waisted jersey or rayon maxi with a slit lets you walk normally; without a slit, a narrow maxi shortens your stride. I tuck in a ribbed tank or a square-neck bodysuit, and the bodysuit is the better choice because a tank creeps out of the waistband over the day. Flat slides or low espadrilles, one long pendant and thin bracelets on one wrist. If your upper arms bother you in a tank, a light open shirt over the top keeps the long line.
18. Plus Size Trench Coat and Jeans Outfit
A trench earns its price at any size, but at 20 I look at the back first. A full trench with a storm flap carries a lot of fabric and turns into a tent unless the belt really cinches. I like double-breasted, water-resistant cotton blend, with the belt tied rather than buckled so it sits softly. Underneath, a thin cashmere or cotton crewneck and straight or slim boyfriend jeans in a medium wash, rolled once at the hem. Low block-heel leather ankle boots, a structured tote and a silk scarf at the neck or on the bag handle cover commutes and changeable spring weather.
19. Plus Size Long Cardigan and T-Shirt Outfit
Longline cardigans only lengthen the body when the knit is fine enough to hang straight. A chunky long cardigan spreads at the hem and adds width right where most people don't want it, so I stick to a fine gauge that falls to the knee or below. Tuck a white or striped cotton tee into high-waisted skinny jeans or ponte pants, then leave the cardigan open. Suede ballet flats or pointed mules, a slouchy leather hobo, studs and a watch. School runs, coffee and long travel days are where this one lives.
20. Plus Size Belted Jumpsuit with Heels
For an evening event, a belted jumpsuit means one piece to get right instead of three. I look for a V-neck or wrap bodice, wide or straight legs and a belt that cinches at the natural waist; a detachable belt lets you swap in a metallic one. Crepe, satin and scuba knit hold their structure, though satin shows every line underneath, so plan your underwear around it. Strappy heeled sandals or pointed pumps lift the leg, and the hem should just skim the shoe. A metallic clutch and chandelier earrings are enough, with hair kept sleek so the earrings show. Weddings, milestone birthdays and big dinners.
21. Plus Size All Black Monochrome Outfit
All black lengthens the body, but flat all black looks like a uniform. I mix textures on purpose: coated skinny jeans, a cashmere sweater, then a tailored blazer or leather moto jacket on top. Each surface catches light differently, so the shape of the outfit still reads in photos. Pointed black suede ankle boots continue the leg line, and a silver pendant or chain-strap bag gives one point of metal. Date nights and gallery openings suit it best.
22. Plus Size Plaid Flannel and Leggings Outfit
An oversized plaid flannel shirt in brushed cotton, worn open, is really a light jacket. Under it goes a fitted white or black tank, and below that, high-waisted ponte leggings, which are thick enough not to go sheer when you bend. That opacity check is the first thing I do with any legging at this size: squat in front of a mirror in good light. Add chunky combat or fleece-lined lace-up boots, roll the sleeves, and pull on a knit beanie and a leather backpack for apple picking, bonfires and fall errands.
23. Plus Size Crewneck Sweatshirt and Biker Shorts
Biker shorts under an oversized crewneck look sporty on purpose, but I check the hem length first. Mid-thigh shorts with a wide waistband stay put, while shorter ones roll up between the thighs within a few blocks. Heather gray or one bold color for the sweatshirt. Chunky white crew socks and retro sneakers lean into the '90s, along with a baseball cap and mini backpack, and hoops with a little lip gloss soften the athletic feel. Good for weekends, errands and travel days.
24. Plus Size Bomber Jacket and Cargo Pants
Bomber jackets end in a ribbed band, and where that band lands decides the whole outfit. I want it at the high hip, never at the widest part, because the rib pulls in and creates a bubble above it. Satin, nylon or cotton twill all work. A plain white tee or fitted tank goes underneath, then relaxed cargo pants in olive or black that taper at the ankle so the outfit isn't wide at both ends. Lug-sole combat boots or high-tops, a thick-strap crossbody and small gold jewelry for concerts and casual days out.
25. Plus Size Velvet Midi Dress Outfit
Velvet catches light on every curve, which can help or hurt depending on the cut. I choose a wrap silhouette, an empire waist or ruching through the midsection, because gathered fabric breaks up the sheen where you'd rather it didn't sit flat. Emerald, sapphire and burgundy look richest in velvet. Stretch velvet is easier to wear than silk velvet and doesn't crush as quickly when you sit. Metallic strappy heels or velvet block pumps, a small beaded clutch and chandelier earrings, and nothing else competing. Anniversary dinners, birthdays and holiday parties.
26. Plus Size Satin Slip Skirt and Knit Top
Bias-cut satin skims curves because the fabric is cut on the diagonal and gives slightly as it hangs, which is also why it shows every line underneath. I wear a slip or smooth, flat-seamed shorts under it. Midi length, just below the calf, in satin or charmeuse. Tuck in a fine-gauge cashmere or cotton-blend sweater in cream or taupe; a chunky knit would bunch at the waist. Pointed flats or barely-there heeled sandals, a fine chain and a structured crossbody take it from work to dinner with nothing more than a shoe change.
27. Plus Size Graphic Tee and Boyfriend Jeans Outfit
A slightly oversized graphic tee, whether a vintage band logo, clean typography or a slogan you actually mean, is the most personal piece on this list. Boyfriend jeans in light to medium wash with a little distressing sit loose, so I half-tuck the tee to show where the waist is; otherwise the outfit goes straight up and down. Roll the hems once to show the ankle and add white leather sneakers, a long pendant and a few rings. A canvas tote or a belt bag worn crossbody keeps it casual for weekend coffee.
28. Plus Size Layered Button Down Shirt Outfit
I size a button-down for the bust and shoulders and wear it open, which sidesteps the gaping you get when a shirt is buttoned over a fuller chest. White or pale blue non-iron cotton, slightly oversized, goes over a camisole or fitted tank tucked into high-waisted straight jeans or cropped trousers. Roll the sleeves to the elbow and add a thin belt on the pants. Suede loafers or leather slides, a structured tote and a gold pendant for casual Fridays, brunch and travel.
29. Plus Size Ponte Pull On Pants and Tunic
Ponte is a double knit, thick and stable, so it smooths without the shine or cling of thin leggings. That's why I like it for pull-on pants with a high elastic waist and a straight or slim leg. The tunic should skim the hips and end below the seat; a curved hem, side slits or soft front pleats stop it from looking boxy. Flat ankle boots or ballet flats, a long pendant and a roomy leather tote. I hand this combination to anyone facing a long workday or a full day of travel.
30. Plus Size Kimono Cover Up and Tank Outfit
A sheer chiffon kimono gives arm coverage without adding heat, and its long open front draws two vertical lines down the body. Let it carry the print, floral or geometric, over a plain white or black tank and high-waisted denim shorts or white jeans. Length is the detail to watch: a kimono that ends mid-thigh cuts across the widest point of the leg, so I prefer knee length or longer. Flat thong sandals or espadrille wedges, beaded necklaces, a stack of bangles and round sunglasses for beach lunches, festivals and vacation walks.
31. Plus Size Peplum Top and Pencil Skirt Outfit
Peplum tops are cut to define the waist and flare over the hips, which suits an hourglass or pear shape best. Where the peplum starts is what I check: it has to begin right at your natural waist, because one that starts lower flares out over the stomach instead. A structured woven or ponte knit holds the shape. A knee-length pencil skirt in a coordinating solid balances the flare. Pointed pumps or heeled ankle boots, a structured satchel and pearl studs keep it ready for presentations and business dinners.
32. Plus Size Striped Sweater and Wide Leg Jeans
Horizontal stripes have a reputation for widening, but a Breton stripe in a relaxed fit with a boat neck mostly broadens the shoulders, and that balances fuller hips. Narrow stripes are easier than wide bands. Navy or black on cream, worn with high-waisted dark-wash wide-leg jeans that fall straight from the hip. White leather sneakers or flat pointed mules, red lipstick, a gold chain bracelet and a canvas tote. I reach for this one for errands or a coffee date.
33. Plus Size Cargo Pants and Crop Top Outfit
High-waisted cargo pants with a relaxed straight leg are comfortable, but bulky side pockets add width at the thigh, so I look for flat, low-profile pockets. The crop top should end exactly at the waistband, in ribbed knit, a boxy cotton tee or a fitted tank; that meeting point is what marks the waist. If a true crop isn't you, pick a top that just grazes the waistband and you'll get most of the effect. Chunky sneakers or platform combat boots, a belt bag and small hoops round it out.
34. Plus Size Relaxed Jumpsuit with Sneakers
Relaxed jumpsuits in Tencel, lyocell or cotton-linen breathe well and fall softly. A slightly dropped crotch or harem-inspired silhouette gives room to move, but too deep a drop shortens the legs, so I keep it subtle. A drawstring or elastic waist defines without pinching. Roll the sleeves and hems a little. White platform sneakers, a backpack purse or canvas tote, and a denim jacket tied at the waist for when it cools down. Travel days and farmers' market mornings.
35. Plus Size Bell Bottom Jeans and Bodysuit
Look for high-waisted bell bottoms in a stretch denim that holds the hips and thighs, then flares from the knee. The flare balances the hip, but only if the hem nearly covers the shoe, so I hem bell bottoms with the platform boots or clogs on and leave just the toe showing. A crewneck or sleeveless turtleneck bodysuit tucks smoothly and stays put. A wide leather belt, a fringe shoulder bag and round sunglasses push the '70s feel for concerts and dinners out.
Gaping Buttons, Riding Hems and Thigh Rub
Three fit problems come up across almost every look on this list. None of them means the outfit is wrong for you; each has a simple fix.
When a shirt pulls open at the bust
If the placket opens between the buttons at bust level, the shirt is too small there even if it fits everywhere else. Go up a size and have the waist darted, or add a small hidden snap or a strip of fashion tape between the buttons. Stretch cotton gapes less than crisp poplin.
When a knit dress creeps upward
Knit dresses and skirts ride up because the fabric grips whatever is underneath it. A slip or smooth shorts give the skirt something to slide against, so it falls back into place when you stand. Lined skirts rarely have the problem.
When thighs rub on hot days
Thin anti-chafe shorts under maxi, midi and wrap dresses solve it for a full day out, and a balm stick handles shorter outings. Cotton and linen breathe; polyester linings trap heat and make rubbing worse, so I check the lining label before buying any summer dress.
Fit Comes Before Trend at Size 20
The number on the tag doesn't decide whether an outfit works. Fit at the waist, bust and shoulder does. Of the 35 looks above, I'd start with whichever one uses a piece you already own that fits well, then shop around it. Winter layers, summer dresses, office suits and weekend sweatshirts all follow the same few rules: fabric heavy enough to hold its shape, hems that end at a narrow point of the body, and one clearly defined waist. Wear what you can move in, and get things tailored, because a small alteration often changes more than a new purchase.
