A full wardrobe and nothing to wear is the most common summer complaint I hear. Heat rules out layers, humidity flattens anything fussy, and gym shorts start to look like a reasonable plan. That's why I give clients formulas: short, repeatable combinations of a top, a bottom and a shoe that work every time. You pick the pieces, put them on and leave. Each of these 35 summer outfit formulas is built for heat first, and I've noted where each one goes wrong, who it suits and how to adjust it for errands, brunch, work or a trip.
Ten Pieces Behind Most of These Formulas
When I build a client's summer formulas, I start with what's already in the closet and check it against a short list. Almost every combination below draws on these ten pieces, so filling a gap here gives you the most new outfits for the money.
- An oversized white button-down in cotton or linen
- Wide-leg linen trousers in a neutral
- High-waisted denim shorts or tailored shorts
- A fitted ribbed tank in black and one in white
- A midi skirt that moves
- A sleeveless midi dress with a defined waist
- Light white jeans
- A cropped denim jacket
- Flat leather sandals or slides
- Clean white sneakers
Keep these in neutrals and your favourite one or two colours, and the formulas swap between each other without any extra thought.
1. White Button-Down Shirt with Denim Shorts and Slide Sandals
This is the formula I'd give anyone who only wanted one. An oversized white button-down in cotton or linen goes over a tank or bralette, with high-waisted denim shorts and flat slides. Half-tuck the shirt so the waist shows, roll the sleeves to the elbow and add big sunglasses. The crisp shirt makes the shorts look intentional. Swap slides for white sneakers on a walking day, and carry a canvas tote. A shirt that's too long will cover the shorts entirely, so I aim for a hem that reaches mid-hip when untucked.
2. Linen Button-Down Shirt with Tailored Shorts and Leather Slides
When it's hot but you need to look organised, a slightly oversized linen button-down in beige, white or a fine stripe tucks loosely into high-waisted tailored shorts in cotton or a linen blend. Simple leather slides finish it, and gold hoops with a structured crossbody sharpen it up. The linen's texture keeps it from looking stiff. It suits a casual office and an afternoon at an outdoor market. I keep this formula in neutrals so the shirt and shorts work with everything else in the wardrobe.
3. Crochet Tank with a Maxi Skirt and Bucket Hat
Crochet adds texture that plain cotton can't. I pair a light crochet tank in cream, black or a soft pastel with a flowing cotton or silk maxi skirt, so the open knit sits against a smooth drape. A bucket hat shades your face, and flat leather sandals with a woven crossbody finish it for picnics, beach walks or sightseeing. An elastic-waist skirt makes it comfortable all day. Most crochet tanks need a nude bralette underneath; a regular bra with visible straps looks unplanned through the gaps.
4. Structured Linen Vest with Matching Wide-Leg Pants
A matching linen vest and wide-leg trousers looks polished without trapping heat, since the vest leaves the arms bare and the trousers let air move. Bone, soft beige or muted sage look expensive in a single tone. Simple leather sandals, a slim belt and fine gold jewelry finish it. It's the formula I use when a client needs to look professional in a heatwave or wants a dinner outfit that isn't a dress. Button the vest for a clean line or wear it open over a cami. Check the armholes before buying; deep ones show your bra.
5. Sleeveless Midi Dress with Minimalist Sandals and Straw Hat
A sleeveless midi in light cotton or linen is the shortest route to being dressed. Solid, striped or a small floral all work. Strappy flats or minimal leather slides, a wide straw hat and a woven tote are enough for brunch or a garden party. The one thing I insist on is waist definition, from an A-line cut, a tie belt or shirring, so the shape doesn't turn into a tent. It also packs flat, which is why it ends up in every holiday suitcase I put together.
6. Silk Camisole with a Midi Skirt and Kitten Heels
Some plans call for something softer. A silk or satin camisole in a pastel or neutral tucked into a flowing midi skirt gives a graceful line for a date, a shower or a long lunch. I mix the textures, putting a silky top with linen, satin or light cotton below so the outfit has some contrast. Kitten-heel sandals add lift without pain, and layered fine necklaces with a small chain-strap bag finish it. Keep a light cardigan or linen blazer nearby; silk is cold the moment the sun goes down.
7. Black Tank with White Wide-Leg Trousers and Statement Sunglasses
Black and white is sharp in summer. A fitted black ribbed tank or square-neck bodysuit goes with breezy white wide-leg trousers in linen or a cotton blend, black sandals and big sunglasses. It works from lunch to drinks with a change of lipstick. The dark top over the pale bottom makes a long line in photos, and a sleek black shoulder bag ties it together. White linen trousers need a skin-tone layer underneath, otherwise the black underwear most people own will show straight through.
8. White Tank Top with Poplin Skirt and Heeled Sandals
Poplin is a crisp, light cotton weave and one of my favourite warm-weather fabrics, because it holds its shape in humidity. A white or black poplin midi or mini makes a plain white tank look deliberate. Tuck the tank in, add a slim belt if there are loops, and wear heeled sandals. A structured bag and simple gold jewelry finish it for a casual office or rooftop lunch. Poplin does crease at the lap when you sit, so I'd choose a cotton with a touch of stretch for long desk days.
9. Flowy Maxi Dress with Flat Sandals and a Wide-Brim Hat
A long, loose maxi keeps you covered and lets air move around your legs on the hottest days. Flat leather sandals or espadrilles, a wide straw hat, big sunglasses and a woven tote make even a trip to the grocery store feel like a holiday. Prints and solids both work. I look for cotton voile or rayon and a side slit for longer strides. Petite clients should check the hem in flat shoes; a maxi that pools on the floor is a trip hazard and shortens the body.
10. Crochet Top with White Jeans and Woven Slide Sandals
Swap a basic tee for a crochet top and the outfit becomes more interesting straight away. A crochet top in cream, tan or soft blush with white straight or wide-leg jeans gives a clean contrast. Woven slides repeat the texture, and a woven or rattan bag pulls the boho-meets-clean aesthetic together. It suits dinners and weekend shopping. Put a nude camisole under open-weave crochet. White jeans in summer should be a lighter denim, since heavy stretch denim gets hot within the hour.
11. Slip Dress with a Thin Belt and Flat Sandals
A slip dress handles almost any occasion with small changes. For daytime, a midi or maxi in cream, sage or navy with a thin leather belt has shape, and flat sandals with a raffia bag keep it easy. Swap to kitten heels and a clutch, and the same dress goes to dinner. The belt is what moves it away from nightwear. A denim jacket tied at the waist adds a weekend feel. Bias-cut slips show every line, so I'd fit this one over smooth, seam-free underwear.
12. Linen Trousers with a Ribbed Tank and Layered Gold Jewelry
Wide-leg linen trousers do more for summer dressing than any other single piece I recommend. The loose leg moves air and the slub texture looks rich without trying. White or beige trousers with a fitted ribbed tank and layered gold chains finish the formula, with chunky leather sandals or woven slides. Tuck the tank in completely so the waist is clear above the volume. It works for casual Fridays, lunch dates and weekends. Linen relaxes as you wear it, so buy trousers that feel slightly snug at the waist.
13. White Tee with Black Capris and Ballet Flats
This one borrows from classic Audrey Hepburn energy: a fitted white baby tee, or a slightly cropped one, with black cropped capris and black ballet flats. The line is clean and graphic, and cat-eye sunglasses add a little old-film glamour. The cropped trouser shows the ankle, which keeps it summery. A red lip or a sleek bun finishes it. Capris cut the leg at its widest point on some figures; I'd choose a pair that ends just above the ankle bone rather than at mid-calf.
14. Coordinated Matching Set with Minimal Sandals
When you can't decide, wear a set. A linen shirt-and-shorts co-ord, a camp-collar shirt with matching trousers or a knit tank with wide-leg pants all remove the guesswork. Beige, olive and dusty blue look current. Minimal leather sandals and a simple shoulder bag finish it. What I like most about a set is the arithmetic: wear it together, then split it, with the top over jeans and the trousers under a white tee, and you have three outfits from two pieces. Buy the set in the size that fits the larger half, and alter the other.
15. Button-Down Shirt with a Mini Skirt and Flip-Flops
Volume on top, short below is the idea here. An oversized cotton or linen button-down, open or half-tucked, goes over a simple neutral mini skirt, with flip-flops or flat sandals. A skirt with a slight sheen or texture adds contrast, and a crossbody with minimal jewelry keeps it light for lunch or shopping. Mind the proportions: the shirt should be roomy but not longer than the skirt, or it looks as though you forgot to put the skirt on.
16. Tank Top with Denim Bermuda Shorts and Low Heels
Bermuda shorts give you real coverage and still feel cool. A simple tank or fitted tee tucked in, with low kitten heels or heeled sandals, lengthens the leg, which matters with a knee-length short. A slim belt, a structured bag and clean jewelry keep it tidy. Dark-wash denim Bermudas look dressier, light-wash ones more casual. On shorter clients, I'd keep the hem just above the knee; Bermudas that land on the kneecap can make legs look short, and a small heel helps balance that.
17. Striped Sweater with White Denim and Flip-Flops
A thin cotton or linen striped sweater is the layer I bring out for breezy evenings. Navy, black or red stripes on white, worn with white jeans, look crisp and coastal from late spring into early fall. Slide sandals or leather flip-flops and a straw bag keep it relaxed. A slim cut with a partial tuck gives shape. Linen-blend knits can stretch along the hem after a few wears, so I'd fold it in a drawer rather than hang it.
18. Bright-Colored Top with a Neutral Breezy Skirt
A strong colour on top with a neutral skirt is a simple way to look cheerful without thinking too hard. Coral, cobalt or emerald draws the eye up, and a beige, white or soft khaki skirt keeps the rest calm. Flat sandals or espadrilles, with minimal accessories, let the colour lead. The skirt can be an A-line mini or a flowing midi. I'd choose the bright colour by holding it under your chin in daylight; the right one makes skin look rested, the wrong one throws shadows.
19. Colorful Blazer over White Separates
Blazers still work in summer if they're unlined. A butter-yellow, soft pink or sky-blue blazer over a white tank and white wide-leg trousers looks polished and fresh. The white base lets the colour carry the outfit. Slides or white sneakers keep it from feeling formal, and rolled sleeves loosen it further. It suits creative offices and client meetings. Pastel blazers show makeup on the collar quickly, so I'd put foundation on well before getting dressed.
20. Button-Down Shirt with a Silk Scarf and Jeans
Take the white shirt and blue jeans you already own and add one accessory: a colorful silk scarf. Tie it at the neck bandana-style, weave it into a ponytail or knot it on your bag strap. It brings colour and pattern to a plain pairing. Flat sandals or loafers finish it, and denim shorts work in place of jeans. A third piece like this is my quickest fix for basics that feel stale. Real silk sits better than polyester and doesn't slip loose every hour.
21. Denim Jacket over a Sundress with White Sneakers
Evening light layers matter, and a denim jacket is the best one. Throw it over any sundress, floral or solid, mini or midi, with clean white sneakers. The jacket adds structure and warmth after sunset, and the sneakers keep the dress casual for concerts and dinners. Choose a light-to-medium wash, cropped or slightly oversized. Tie it around your waist in the heat of the day. A jacket that ends at the waist suits a midi best; a longer one works better over a mini.
22. Halter Dress with Strappy Heels and Minimal Jewelry
For dressier plans, a halter dress shows the shoulders and collarbone without a lot of fabric. Pair a midi or mini halter with strappy heels in a neutral or metallic shade. Skip the necklace, since the neckline already frames the face, and choose statement earrings instead. A small clutch or chain-strap bag completes it for weddings, rooftop parties or anniversary dinners. Pick cotton voile or crepe so you stay comfortable into the night, and check the bra situation before the day.
23. Lightweight Jumpsuit with Platform Sandals and a Crossbody Bag
A sleeveless or cap-sleeve jumpsuit in cotton, Tencel or linen is a whole outfit with no matching required. A defined waist from elastic, a tie or seams stops it from looking like a sack. Platform sandals add height with a retro edge, and a crossbody keeps things practical for brunch, shopping or travel. Go for a solid neutral for the most use, or a subtle stripe for more character. Roll the hems for a relaxed look. Always test the torso length sitting down; it's the most common fit problem I see in jumpsuits.
24. Oversized Graphic Tee with Biker Shorts and a Baseball Cap
When comfort comes first, an oversized graphic or vintage-washed tee over black biker shorts gives a balanced shape: roomy on top, fitted below. White sneakers and a baseball cap lean into the athleisure energy, and a canvas tote with small hoops finishes it for walks, coffee and travel days. The tee should end around mid-thigh to look intentionally oversized. A faded print looks more relaxed than a crisp new one.
25. Polo Shirt with a Linen Midi Skirt and Loafers
Polos have moved well beyond tennis clubs. A slim or slightly cropped polo in a solid neutral tucked into a flowing linen midi looks preppy and current. Leather loafers or backless mules finish it, with a slim belt and a structured tote. The firm knit above the soft skirt is what makes it work. It suits casual offices and lunch meetings. Choose a polo with a short placket and a soft collar; a stiff one looks like a uniform.
26. Tank Top with Cargo Pants and Canvas Sneakers
Cargo pants mix function with a relaxed shape. A light cotton or twill pair in olive, khaki or cream balances best with a fitted tank or crop top, and white or neutral canvas sneakers keep it comfortable all day. The pockets add enough detail that you need few accessories, maybe a cap and a crossbody. I'd go high-waisted. Check where the side pockets sit; if they land at the widest part of your thigh, they add width there.
27. Floral Sundress with White Sneakers
White sneakers take the sweetness out of a floral sundress. Choose a mini or midi in cotton, rayon or a linen blend, and keep the sneakers clean and simple. A denim jacket around the waist adds a casual layer. It's an easy formula for errands, lunch or a day exploring a new city. I'd avoid chunky sneakers with a delicate dress, since they overpower it; a low, slim pair keeps the balance.
28. All-White Outfit with a Denim Shirt Layer
All white feels clean and fresh in summer. White jeans or wide-leg trousers with a white tank or tee, plus an open denim shirt on top, break up the single colour with a little blue and texture. A printed belt in snakeskin or a subtle animal pattern adds interest. Neutral sandals or white sneakers finish it, and a shoe change takes it into the evening. Because the base is plain, your bag and jewelry get noticed. White on white shows any difference in tone, so match warm whites with warm whites.
29. Tube Top with Wide-Leg Pants and Heeled Sandals
A tube top gives a clean line across the shoulders that suits the volume of wide-leg trousers. Choose a smocked or structured style that stays up, with high-waisted linen or flowing trousers. Heeled sandals lengthen the legs. Wear flats for brunch, then heels and statement earrings for dinner. A clutch or mini shoulder bag finishes it. Tube tops are hard work on a larger bust; I'd steer those clients to a bandeau with a hidden halter strap.
30. Paperbag Shorts with a Cropped Blouse and Mules
Paperbag-waist shorts gather at the waist, which gives shape on many body types. Choose a light poplin, linen or cotton blend, and tuck in a cropped blouse or fitted tank so the waist detail shows. Backless mules or slides, a structured handbag and simple hoops finish it for a casual workplace or weekend plans. The gathers add some bulk at the front, so I'd skip this cut if you're short-waisted or prefer a flat front.
31. White Jeans with a Striped Top and Wedge Espadrilles
White jeans with a striped top is one of the oldest formulas there is, and it still works. White straight or wide-leg jeans go with a navy-and-white stripe, either a boatneck tee or a relaxed button-down. Wedge espadrilles add height and summer texture, and a woven tote with simple gold jewelry finishes it. Choose a slim top and half-tuck it. Stripes go with almost everything else you own, which is why I count them as a neutral.
32. Knit Sweater Vest with Linen Trousers or Tailored Shorts
A light knit sweater vest worn over a tank, or on its own, adds a layer without heat, because the arms stay bare. With wide-leg linen trousers it looks smart; with tailored shorts it's more casual. Neutral sandals or loafers, a fine chain and a structured bag finish it. It suits mornings that start cool and warm up by noon. Choose fine-gauge cotton or a linen blend; anything woolly is too warm by lunchtime.
33. Off-Shoulder Top with High-Waisted Shorts and Statement Earrings
An off-shoulder top frames the collarbone and shoulders, and high-waisted denim or tailored shorts keep the shape balanced. Flat sandals or espadrilles finish it. Bold earrings are the accessory that matters here, since the bare shoulder line leaves room for them. It suits date nights and holiday dinners. Choose a top with elastic at both neckline and sleeves so it stays put, and add a low bun so the neckline isn't hidden.
34. Culottes with a Sleeveless Top and Straw Bag
Culottes are wide-leg trousers cut to a cooler, cropped length. Neutral culottes in cream, taupe or black go with a sleeveless blouse or shell in a complementary shade. The wide leg moves nicely, and a big straw bag gives it a holiday feel. Flat sandals or low block heels keep the line long. It suits creative workplaces and weekend brunches. A top that ends at the natural waist helps the proportions, especially on petite frames where culottes can look heavy.
35. Swimsuit as Bodysuit with Wide-Leg Trousers and a Belt
A one-piece swimsuit can double as a bodysuit. A black, white or beige style with high-waisted wide-leg trousers in the same shade makes a single column of colour. Add a belt at the waist and finish with flat sandals or heeled mules. Silver jewelry gives a cool contrast, and a light linen blazer or open shirt over the shoulders adds polish. It takes you from beach to bar on holiday. Swimsuits have no snaps at the crotch, so plan the bathroom trip; it's the one downside clients mention.
Short Torso, Long Legs and Other Formula Tweaks
A formula is a starting point, not a uniform. The same pieces sit differently on different bodies, and small adjustments make most of them work for anyone.
- Short torso: wear tops untucked or front-tucked only, and choose mid-rise rather than very high-waisted bottoms.
- Long torso: high waists and a full tuck balance the line.
- Petite: keep hems either above the knee or at the ankle, and choose a pointed or open shoe to extend the leg.
- Fuller bust: pick V-necks and wrap tops over tube tops and high crew necks.
- Fuller hips: let volume sit on top and keep bottoms smooth and straight.
Making Repeat Pieces Last All Summer
Wearing the same pieces on repeat means they wear out faster, so care matters. Wash linen and cotton cool and line-dry them in the shade so colours don't fade. Turn white tees and tanks inside out, and treat underarm yellowing early with a soak rather than waiting until autumn. Give leather sandals a day off between wears so they dry out from sweat, and they'll keep their shape far longer.
Four or Five Formulas on Repeat
Getting dressed in summer shouldn't take more energy than the day ahead. With a few of these formulas memorised, most mornings come down to picking three or four pieces you already own and putting them together. The answer isn't more clothes, but knowing which combinations keep you cool and feel like you. Swap colours and textures, adjust for your shape, and once four or five formulas become your favourites, wear them on repeat. That is exactly what a formula is for.
