There’s something truly captivating about coastal grandmother style—a fashion aesthetic that goes beyond clothing and becomes a serene way of living. Picture Diane Keaton’s effortless charm in Something’s Gotta Give, barefoot walks on a sun-dappled garden path, the gentle hum of a ceiling fan, and the slow clink of ice in a tall glass of tea. This look is all about ease, grace, and a timeless connection to the laid-back luxury of seaside living.
Whether you live steps from the ocean or just dream of that relaxed porch swing vibe, coastal grandmother style invites you to embrace simple elegance through a carefully curated summer wardrobe. It’s a celebration of breathable fabrics, natural textures, and quiet sophistication—a style that’s as comfortable as it is chic. Here are nine wardrobe essentials to help you embody this lovely aesthetic all summer long.
1. The Crisp White Button-Down: Your Style Staple
If coastal grandmother style had a uniform, it would be the white button-down shirt. This versatile piece is endlessly polished yet effortless. Wear it over your swimsuit on a warm day, tuck it into airy linen trousers, knot it casually at the waist, or leave it open over a simple tank. Opt for breathable materials like 100% cotton or linen blends to keep cool when the temperatures rise.
Style tip: Don’t hesitate to try a short-sleeve version for a lighter, summery feel that still captures that classic, easygoing vibe.
2. Relaxed Linen Trousers: Comfort Meets Refinement
Nothing says summer like linen trousers that float lightly over your legs. The natural fibers keep you cool and comfortable, while the relaxed fit flatters without clinging. Neutral tones like oat, ivory, or soft sage are perfect for mixing and matching with your favorite tops. These trousers effortlessly elevate a casual tank or tee and offer a breezy alternative to jeans.
Pair them with raffia accessories or crisp cotton poplin shirts to bring out their coastal charm.
3. The Nautical Striped Sweater: A Timeless Nod to the Sea
Even in summer, mornings by the coast can call for a light sweater. The iconic blue and white striped sweater is a quintessential piece that evokes memories of sailing trips and New England charm. It’s perfect for draping over your shoulders on a sunny afternoon or throwing on with denim shorts as the evening cools.
Stripes never go out of style and add an instant coastal touch to your outfit.
4. The Flowy Midi Dress: Feminine and Free
A flowy midi dress is a summer wardrobe hero—lightweight, airy, and effortlessly feminine. Look for fabrics like cotton, gauze, or linen in classic patterns such as florals, gingham, or soft, summery solids in shades of blue, white, or blush. This dress moves with you, whether you’re tending your garden or setting the table for an outdoor dinner.
Slip on sandals or espadrilles, and you’re set for almost any summer occasion.
5. A Woven Straw Hat: Practical Elegance
A wide-brimmed straw hat is as functional as it is stylish—perfect for shielding your skin from the sun while adding an instant air of seaside sophistication. Pair it with oversized sunglasses and a linen sundress to channel that iconic Nancy Meyers film moment: timeless, elegant, and effortlessly cool.
6. Neutral Espadrilles or Ballet Flats: Shoes That Speak Softly
Your summer footwear should combine comfort and classic style. Espadrilles—whether in canvas or leather—offer breezy elegance, while ballet flats bring a touch of Audrey Hepburn grace. Stick to neutral hues like tan, ivory, or blush to keep your palette soft and cohesive, maintaining that muted, classic coastal vibe.
7. The Perfect Straw Tote Bag: Functional and Charming
No coastal grandmother wardrobe is complete without a straw tote bag. Whether you’re heading to the farmers’ market, a picnic, or an evening on the dock, a good straw tote is your summer sidekick. Look for structured or slouchy oversized styles with leather or canvas accents to elevate your look.
Inside, you’ll find your essentials—sunglasses, sunscreen, a paperback novel, and maybe a linen scarf—because this style is about the life you’re living, not just the clothes you wear.
8. Minimal Jewelry: Subtle Sophistication
The beauty of coastal grandmother style lies in its simplicity. Choose delicate, well-crafted jewelry—small pearl studs, a fine chain necklace, or a dainty tennis bracelet. These understated touches add polish without overpowering your look.
Think heirloom-inspired or handmade pieces that feel personal, timeless, and quietly elegant.
9. Well-Fitting Denim: Casual and Classic
Denim is a year-round essential, and for summer, a lighter wash with a relaxed, cropped straight-leg cut is ideal. This style pairs beautifully with sandals and feels cool on warm days. Combine your jeans with a tucked-in white blouse, a straw hat, and a raffia bag for a classic coastal look.
Add a spritz of citrus perfume, and you’re ready to embrace the day with effortless style.
Bringing It All Together: Style as a Way of Being
Coastal grandmother style isn’t just about fashion—it’s about feeling unhurried, thoughtful, and beautifully grounded. It’s dressing for the life you want: slow mornings, al fresco dinners, linen sheets fluttering in the breeze, and calm woven into every moment.
As you build your summer wardrobe, focus on timeless pieces that you’ll love wearing season after season. Choose breathable fabrics, soft colors, and accessories that remind you of the sea—even if you’re far from the shore.
Because coastal grandmother style isn’t tied to age; it’s a mindset. A quiet confidence that says you are exactly where you’re meant to be.
