The coastal grandmother aesthetic has outlasted most summer trends because it's built on clothes people already understand: crisp button-downs, loose linen, a cashmere sweater knotted over the shoulders, a straw hat and a woven bag. The palette comes straight off the shoreline, white, cream, sand, soft blue and pale green. As a wardrobe stylist, what I like most is how few pieces it needs. The same striped top and linen pants turn up again and again below, worn three different ways. Here are 20 outfits for market mornings, garden lunches and evenings by the water.
Building This Look From Your Own Closet
Before buying anything new for this style, I count how often each piece turns up. In the twenty outfits below, a handful of items do almost all the work, and most people already own several of them.
- A white or light blue button-down, worn tucked, open or knotted.
- A navy-and-white striped top, either a tee or a sweater.
- Wide-leg linen pants or white straight jeans.
- A cream or oatmeal knit to drape over the shoulders.
- A straw hat with a brim wide enough to shade the face.
- Pearl studs and one flat, walkable sandal or espadrille.
If you own four of these, buy the missing ones first and skip the rest of the list until you've worn them. A straw hat changes more outfits than anything else, so it's my first buy for anyone starting from scratch. Dresses, caftans and blazers come later, once the basic pieces are earning their space.
1. Linen Button-Down And Shorts With Sweater And Straw Hat
A blue linen button-down with relaxed shorts in the same shade makes one long block of color, which is why this simple look feels finished. A half-zip sweater draped over the shoulders is there for the breeze and can be knotted at the neck once the sun comes out. A straw lantern hat keeps the sun off without adding weight. Small pearl studs and fisherman sandals finish it. Tonal blue only works when the two linens are close in shade, so I'd buy them together or hold them side by side in daylight. Two blues that are nearly the same look like a mistake.
2. Striped Sweater Over White Maxi Dress With Clogs
A long white maxi dress is a clean base, and a navy striped cardigan on top supplies the classic nautical reference this style leans on. Stripes on a cardigan read as seaside without tipping into sailor costume. Suede slip-on clogs add an unexpected texture and keep it comfortable, and a woven straw tote holds market finds or a bunch of flowers. A plain pearl pendant finishes it. Suede and dew-wet grass are a bad mix, so I keep these clogs for dry mornings. A white dress also shows the dye from a dark cardigan in summer sweat, so I wash the cardigan once before the first wear.
3. Striped Tee With White Linen Skirt And Fisherman Sandals
A black-and-white striped tee tucked into a white linen skirt is a simple pairing that still looks dressed. The skirt moves well and stays cool in the heat. I'd pick a tee with a little weight to it, because thin jersey tucked into linen bunches at the waistband and shows the ridge through the skirt. A straw lantern hat, pearl earrings and tan fisherman sandals keep the rest practical, and a woven bag adds texture. Black stripes are sharper than navy ones; they suit people with high-contrast coloring, and on softer coloring I'd switch to navy.
4. Open White Button-Down Over Tank With Linen Pants
Here a soft gray tank and white linen pants make a tonal base, with a white button-down left open over the tank so a strip of gray shows down the front. That open shirt is the layering move I use most in this style. It adds a second layer without heat, and it covers the upper arm for anyone who prefers it. Black oval sunglasses add a bit of edge, espadrille flats keep it summery, and a pearl bracelet supplies the only shine. Poplin, cotton and linen all breathe, so the outfit stays cool on a hot afternoon of errands.
5. Linen Shirt With Striped Wide-Leg Pants And Heels
Coastal grandmother style can go to dinner, and this is how. Striped wide-leg pants carry the outfit, with a neutral linen button-down tucked in to keep the waist clear. Block heels instead of flat sandals add height you can still walk in on a patio or a wooden deck. A woven clutch or structured straw bag keeps the texture going, and a strand of pearls finishes it. Vertical stripes on wide pants lengthen the leg; horizontal or very wide stripes do the opposite. When I fit these, I make sure the hem just covers the top of the heel, so the stripe runs nearly to the floor.
6. Striped Tee With Denim Overalls And Basket Bag
Denim overalls feel nostalgic, and they slot into this style more easily than you'd expect. A striped long-sleeve tee underneath, a straw lantern hat on top and a woven basket bag, the kind Jane Birkin made iconic, give them the seaside look. White sneakers keep it comfortable for a long day on your feet. Overalls are fussy to fit: the bib should sit flat, and the straps should be adjustable so the crotch doesn't pull when you bend. For a waterfront flea market or a casual outdoor gathering, it's the playful one of the twenty.
7. Cable Knit Sweater With White Shorts And Sun Hat
A cream fisherman cable-knit sweater over white denim shorts keeps everything in one color and lets texture do the work. The chunky knit against smooth denim is the whole point. An oversized straw sun hat, pearl earrings and fisherman sandals finish it, and a canvas tote holds sunscreen, a paperback and a towel. A heavy cable sweater is warm, so this is an outfit for a windy shoreline rather than a still, hot afternoon. I'd pick cotton cable over wool for the beach; it handles sand and sweat and goes in the washing machine.
8. Turtleneck With Linen Pants And Raffia Tote
A thin turtleneck with airy linen pants sounds odd, but it suits those in-between days when the breeze carries a chill. A fine-gauge knit sits smoothly under nothing at all, and the linen keeps the legs cool. Woven leather sandals bridge the two seasons, and a raffia tote bag adds the coastal texture. A straw hat and pearl studs finish the look. Choose a cotton or silk-blend turtleneck rather than wool for this, since a wool neck against the skin gets itchy once the afternoon warms up.
9. Striped Button-Down With Denim Shorts And Sneakers
Plain denim shorts can take on this style with a few swaps. Instead of a basic tee, I'd use a striped button-down, which looks more put together and can be worn open as a light jacket. White sneakers handle a long day of errands, and a canvas tote with a nautical look carries everything. Pearl earrings give the casual base some polish, and a soft pastel or neutral cap keeps the sun off. The shirt should end around the hip, short enough not to cover the shorts entirely. A shirt that hangs past the hem makes it look as though you forgot your shorts.
10. Cashmere Sweater With White Jeans And Loafers
A cashmere sweater in cream, sand or pale blue worn with white jeans is the most refined outfit on this list, and it's very simple. Wear the sweater loose or knot it over the shoulders. Tan or nude leather loafers carry the neutral color down to the feet, so the leg looks longer. A raffia bag and a wide-brim sun hat add the beach texture. Cashmere and white denim both mark easily, and sunscreen and self-tanner stain both, so I put lotion on well before I get dressed.
11. White Button-Down With Chinos And Leather Belt
For a more polished version, a crisp white button-down tucked into tailored beige or khaki chinos with a simple leather belt makes a clear waistline. Slip-on loafers keep it practical, and a woven tote or leather satchel carries what you need without bulk. Pearl or gold studs add a small gleam. I'd pick chinos with a slight taper and a hem that clears the loafer's top line, because full-length chinos break over a loafer and look borrowed. This one suits a casual office or a lunch meeting.
12. Flowy Midi Dress With Espadrilles And Straw Hat
A flowy midi dress in a soft floral or a solid pastel shows the romantic side of the style. The fabric matters most: light cotton, gauze or a linen blend that catches the breeze. Espadrilles with ankle ties add height and stay on, and a wide-brim straw hat and raffia tote finish it. Thin gold or pearl drops are all the jewelry I'd add. Gauze is often semi-sheer in direct sun, so check it outdoors before you commit. For a garden party or an evening walk at golden hour, it's the softest outfit here.
13. Chunky Knit Sweater With Wide-Leg Cream Trousers
An oversized chunky knit in oatmeal, sage or soft gray balances wide cream trousers because both pieces are generous; a fitted top would look lost above them. Loafers or ballet flats in a muted tone keep it clean, and a plain leather tote and a silk scarf loosely tied at the neck finish it. Volume on both halves needs one narrow point, so I'd push the sweater sleeves up to show the wrists. If you're petite, try a cropped chunky knit instead so the trousers can carry the length. Wear it on cool mornings or for an evening around a beach fire.
14. Trench Coat With Linen Button-Down And White Jeans
A beige trench worn open over a linen button-down and white jeans is my spring uniform for this style. Tie the belt loosely behind your back so the coat keeps its shape while hanging open. The trench handles wind and light rain, which linen alone can't. Ballet flats or low sneakers keep it walkable, and a light linen or cashmere scarf, a structured tote and pearl studs or small gold hoops finish it. Trench length decides who it suits: a knee-length coat flatters most heights, while a mid-calf one needs some height to avoid swamping the frame.
15. Chambray Shirt Dress With Espadrilles And Straw Tote
A washed-blue chambray shirt dress is about as easy as dressing gets. Roll the sleeves loosely and tie a woven straw belt at the waist to give it shape and add a natural texture. Flat espadrilles, a wide straw hat, big sunglasses and a structured straw tote cover the rest, with a few gold bangles for shine. Chambray softens with every wash, so a stiff new dress will feel much better by its third outing. I'd skip the belt if the dress has a self-tie already; two waist details fight each other. Wear it sightseeing or for a casual lunch outdoors.
16. Navy Stripe Sweater With White Cropped Pants And Boat Shoes
A navy-and-cream striped sweater is the most maritime piece in the whole style. Pair it with crisp white cropped pants that show a little ankle, and brown leather boat shoes, which were designed for grip on wet decks and are just as comfortable on a harbor walk. A canvas tote and pearl earrings or a fine gold chain finish it. Boat shoes are traditionally worn without socks, so I'd add no-show liners to keep the leather from getting sweaty and stretched. It's a good outfit for an evening by the marina.
17. Linen Caftan With Sandals And Straw Accessories
A loose linen caftan in a soft neutral or pale blue stripe works as a beach cover-up and as a full outfit. Its loose cut stays away from the skin, so it keeps you cooler than anything fitted. Flat leather sandals, a wide straw hat, big sunglasses and a woven basket bag finish it, with a few wooden or gold bangles. A caftan with no shape at all can look like a robe in town, so I look for one with a slight V-neck or a drawstring at the waist. It goes from a lounge chair to a boardwalk café in a minute.
18. Cream Blazer With Tank And Wide-Leg Linen Trousers
A light cream blazer over a plain white tank adds polish without looking corporate. Wide-leg linen trousers in a matching neutral keep it soft and cool. Tan loafers or low block-heel sandals, a structured tote, a fine gold watch and small earrings finish it. Unlined or half-lined blazers are the ones to look for in summer; a fully lined one traps heat. The blazer's shoulder seam should sit right at the edge of your shoulder, the one fit point a tailor can't fix cheaply. For a gallery opening or a dinner a step up from casual, this is the one.
19. Floral Midi Dress With Cardigan And Wedge Espadrilles
A floral midi in muted blue, lavender or blush gives this style its garden-party side. A light cardigan in a matching neutral sits over the shoulders for when the breeze picks up. Wedge espadrilles add height that's comfortable on grass, where a thin heel sinks. A straw crossbody or top-handle bag and a single strand of pearls finish it. I'd pick the cardigan color from the lightest shade in the print, which ties them together without matching too closely. It's an easy choice for a spring wedding guest or a sunset drink near the water.
20. Breton Stripe Tee With Cropped Jeans And Canvas Tote
A classic Breton stripe tee in navy and white earns its place in this closet more than any other piece. Tuck it loosely into cropped straight-leg jeans, add white sneakers for walking, and sling a canvas tote over the shoulder. A straw hat and small gold hoops finish it. Most Breton tees are boxy and a touch short, which is why the loose tuck works. A long one hanging over the jeans hides the waist completely. Wear it for a coffee run, a library trip or a picnic in the park.
Washing and Storing the Natural Fabrics
This style depends on linen, cotton, cashmere and straw, and each one wears out differently. Cared for properly, they last for years and look better with age.
Linen and White Denim
Wash linen cool and hang it to dry; a hot dryer shrinks it and sets creases. Iron while it's still slightly damp if you want it crisp. Turn white jeans inside out and wash them cold, and keep chlorine bleach away from stretch denim, since it weakens the elastic fibers and leaves the fabric baggy. Wash striped cotton tops cold with a color-catcher sheet for their first few washes, so loose navy dye can't tint the white stripes.
Cashmere and Straw
Hand-wash cashmere in cool water with a gentle wool wash, press the water out in a towel and dry it flat. Fold it rather than hanging, or the shoulders stretch. Moths love it in storage, so put it away clean with cedar. Straw hats should be stored crown-down or on a hat stand, kept dry and never crushed in a bag. If one gets wet, reshape it by hand and let it dry slowly.
A Wardrobe That Gets Better With Wear
This style lasts because it's built on comfortable, plain pieces rather than a passing trend. Natural fabrics, a soft palette and accessories that feel collected rather than bought as a set will work across seasons. Twenty outfits above use far fewer than twenty pieces, which is the real lesson. Start with a linen button-down, white trousers, a striped top, a cashmere sweater and a straw hat. Wear them for a month before you add anything else, and you'll see quickly which gaps actually matter.
