Why the striped shirt defines coastal grandmother style this summer

The striped shirt is doing the most this summer, and that is exactly why it works. It can look like a borrowed menswear staple, a Hamptons lunch uniform, or the easiest way to make white linen pants feel intentional instead of lazy. In the coastal grandmother wardrobe, it is the piece that ties together the Nancy Meyers polish, the beach-adjacent ease, and the kind of quiet luxury that only looks casual from a distance.

The shirt that carries the whole mood

Coastal grandmother style entered the conversation in March 2022, when Lex Nicoleta coined the term on TikTok and turned a very specific kind of dressing into a full-blown visual shorthand. The look is built around crisp white buttons, straw hats, linen pants, and that effortless seaside neatness that never quite tips into costume. The striped shirt slots into that formula better than almost anything else because it gives you structure without stiffness, and pattern without noise.

What keeps it from feeling trendy-for-trendy’s-sake is the history baked into the stripe itself. The Breton striped shirt, or marinière, is tied to the French Navy, with one heritage source tracing the uniform decree to March 27, 1858. That military origin matters because it explains the shirt’s strange durability: it started as function, then moved into civilian wardrobes, and never really left.

Why the stripe still reads current

The stripe is not resting on nostalgia alone. Editorialist’s summer coverage puts stripes in the middle of the spring/summer 2025 and 2026 conversation, with Proenza Schouler, Prada, Toteme, and Schiaparelli all part of the revival. That is the real tell: when runway houses with very different instincts keep circling back to the same motif, the piece is no longer a gimmick. It becomes a uniform.

There is also the way stripes behave on the body. A good striped shirt gives the eye a rhythm, especially in linen or cotton-poplin, which are the materials doing most of the work this season. Linen brings that dry, breezy texture that handles heat without clinging. Cotton-poplin sharpens the silhouette, so even a loose cut still feels considered. That is why the same shirt can look smart over tailored shorts at lunch and just as right half-tucked into wide-leg trousers at dinner.

What makes one striped shirt worth it and another merely expensive

This is where the price-to-value question gets interesting. Editorialist’s current striped-shirt edit, last updated on July 1, 2026, shows The Row striped shirts starting at $545 and Brunello Cucinelli striped shirts starting at $376. Those numbers tell you the category is not one-size-fits-all. You are not just paying for a stripe, you are paying for how the stripe is cut, how the fabric falls, and how long the shirt can stay in rotation before it looks tired.

At the top end, the value has to show up in the details. The Row earns its price when the shirt has that exacting drape and restraint, the kind that makes a simple blue-and-white stripe look almost severe in the best way. Brunello Cucinelli is a different proposition: the price sits lower, but the appeal is still in the handfeel, the finish, and the sense that the shirt will age into your wardrobe instead of aging out of it. That is the difference between a shirt you wear for one summer and a shirt that keeps working when the season changes.

If you want the investment test in plain language, look for three things:

• Fabric that feels cool and breathable, not paper-thin
• A cut that skims the body instead of clinging to it
• Finishing details that hold up after repeated wear, like a clean collar, steady placket, and stripes that do not feel printed-on cheap

Róhe, Nili Lotan, Polo Ralph Lauren, and Matteau sit in the same conversation because they all understand the balance coastal grandmother needs: relaxed, but never slouchy; polished, but never precious. That is the sweet spot. If the shirt can only do one look, it is a novelty. If it can move from beach brunch to city errands without changing character, it earns the spend.

How the shirt gets styled without looking overworked

The best coastal grandmother outfits do not pile on the theme. They keep the shirt at the center and let everything else calm down around it. A striped linen button-down with white trousers reads cleaner than a full closet’s worth of “resort.” A cotton-poplin version with rolled sleeves and gold earrings can look sharper than a blazer in July. The point is not to decorate the look with nautical references. The point is to let the stripe do the signaling.

That is also why the shirt has cross-generational pull. The Royal Museums Greenwich describes the striped T-shirt as an enduring favorite and notes wearers including Picasso, Kurt Cobain, and the Duchess of Cambridge. That range says everything. The shirt can look intellectual, rebellious, or polished depending on the rest of the outfit, which is a rare trick for something so basic.

Why this is the summer basic that keeps winning

The striped shirt keeps resurfacing because it solves a summer problem that most clothes do not: it gives you presence without heat, shape without effort, and polish without obvious branding. In a market where coastal grandmother dressing is still tied to crisp white buttons and beachside ease, stripes have become the clearest shorthand for the look. They feel expensive when the fabric is right, and flat when it is not.

That is the real battleground this summer. The best versions are not selling fantasy, they are selling longevity. A well-cut striped shirt in linen or cotton-poplin does not just fit coastal grandmother style, it explains why the style keeps finding new buyers every season.
