Forget the Blazer—Tops: Button Up Shirts Are Spring 2026’s Power Move

The most stylish people I know have quietly stopped reaching for blazers. Instead? They’re wearing oversized button-up shirts. It started on the Spring runways, where designers doubled down on relaxed tailoring and menswear proportions. Then street style took over. Outside shows in Paris and Copenhagen, it wasn’t structured jackets getting photographed—it was striped shirts, flannel layers, and oversized poplins worn with the kind of confidence that can’t be faked. The message was clear: looking polished is out. Looking effortlessly pulled together is in. That’s why Tops: Button Up Shirts feel so relevant right now. They do the work without looking like they’re trying. My favorite styling trick is wearing one half-buttoned over a ribbed tank with loose jeans and loafers. A little undone. A little borrowed. The kind of outfit that looks even better at 6 p.m. than it did at 9 a.m. I’ve had my eye on the Zether Shirt from SNDYS. The mocha stripe feels expensive without being flashy, and the oversized silhouette captures that relaxed coastal mood that’s dominating fashion right now. For something brighter, the cranberry-striped x REVOLVE Estelle Shirt delivers the same easy energy with a little more personality. If you’re into the new wave of prep that’s showing up everywhere from TikTok to fashion week, Line & Dot absolutely nailed it with the Marmalade Shirt. The crisp pinstripes and elongated silhouette feel scholarly in theory, but in practice it’s more fashion-insider than Ivy League. For weekends near the water, I can’t stop thinking about the La Mer Shirt from L*Space. The maritime embroidery taps into the coastal nostalgia trend that’s everywhere this season, from luxury collections to vintage markets. Meanwhile, Show Me Your Mumu‘s Button Up Coverup is exactly the kind of piece I’d throw over a swimsuit after a beach day and somehow end up wearing straight to dinner. That’s the beauty of a great shirt—it adapts. And if the return of ’90s grunge has caught your attention, look at the Audriana Oversized Flannel Top from superdown. The oversized plaid silhouette feels like something a model would pull from a vintage shop and wear all season. Even Central Park West is tapping into the movement. The collared Sienna Sleeveless Cable Vest delivers that same menswear-inspired attitude in a lighter, spring-ready form. Fashion loves a complicated trend. This isn’t one of them. Buy a great shirt. Wear it slightly oversized. Roll the sleeves. Leave a few buttons undone. That’s where Spring 2026 is headed.
