This post is all about the Coastal Auntie.

If you’ve ever dreamed of being the cool aunt—sipping a chilled Sancerre on a seaside terrace—the Coastal Auntie aesthetic is for you.

The Coastal Auntie embodies the perfect blend of the cool rich single aunt and the coastal grandmother aesthetic. But this isn’t your grandmother’s linen collection; she’s unfiltered yet effortlessly charming. Think relaxed layering, perfectly undone hair, and looking like you own a boat (even if you don’t).

The coastal auntie throws dinner parties straight out of a Nancy Meyers film—candlelit seafood spreads, with crisp white wine, and a perfectly curated playlist. She lives for breezy linen moments, chic sundresses, and timeless accessories. And she’s mastered the art of looking like she just got back from a long weekend in Montauk—because she probably did.

To channel her energy, you need staples that are timeless, comfortable, and effortlessly versatile—think coastal textures, neutral tones, and relaxed tailoring with just the right amount of polish.

In this post, we’ll break down the Coastal Auntie must haves, from classic striped linens to airy, beachy layers. Plus, we’ll show you exactly how to nail the coastal fashion trends for 2025. Ready? Let’s get into it.

Below is your complete Coastal Auntie Guide.

The Outfit Deets.

Nautical Stripes, But Make It Chic

Stripes and linen are the unofficial uniform of the Coastal Auntie—timeless, breezy, and effortlessly polished. Whether it’s a flowy striped dress, crisp linen trousers, or an airy midi skirt, these staples instantly channel coastal fashion style without feeling overly preppy.

Cozy by the Coast

A crewneck sweater is a non-negotiable. You need that “just borrowed from my sailor boyfriend” energy. Opt for soft neutrals—cream, navy, or heather gray—and drape it over your shoulders when the sun’s out, then throw it on when the breeze rolls in.

Breezy & Effortless

Nothing screams coastal chic fashion like a flowy sundress. Stick to lightweight fabrics like cotton, linen, or gauze in muted tones or delicate prints. This is your go-to for spring brunch outfit ideas or casual beach walks—just add a tote bag and sandals, and you’re golden.

Coastal Carryalls

Your bag game matters. The Coastal Auntie needs two staples: a woven straw bag for chic summer outings and a boat tote bag for practical yet stylish beachside essentials. Go for structured, high-quality materials that add to the overall polished-yet-relaxed vibe.

Tidal Treasures

Accessories make the outfit. Think dainty gold jewelry, oversized sunglasses, and a chic bucket hat to keep things feeling curated yet effortless. Opt for natural textures—like pearl earrings, seashell claw clips, and raffia details—subtly tie everything together.
