Baseball T-Shirts & Raglan Tees Are Spring 2026’s Top Trend

There’s a new archetype of sporty style gaining traction among the fashion set: the cool-girl tomboy. It’s athletic-adjacent, with one item similar to what you’d wear for the 40-yard dash or to kick a ball back and forth, but the end result is always closer to downtown chic than track star. Exemplar outfits include a tech-y windbreaker teamed with lace-trimmed shorts, side-stripe track pants paired with pointed-toe pumps, and, most popular of late, a baseball-style raglan T-shirt styled with separates that wouldn’t fare well on the diamond.

Not to be confused with the performance jerseys MLB players wear on the field, the baseball tees I’m talking about are casual, made of soft cotton, and come with contrast-color raglan sleeves. You’ll find them in the vintage T-shirt section of a thrift store or worn by an underdog little league team at the heart of an inspirational ‘70s sports movie, like the ones I’d watch in P.E. class when it was too rainy to go outside and play. Only now, in 2026, you’ll find them anywhere a fashion girl goes.

At the most recent New York Fashion Week, my fellow runway guests looked ready for a Yankees game (or Mets game, depending on their allegiance). Combing through Marie Claire’s celebrity street style coverage, you’ll read about trendsetters wearing baseball T-shirts with slip skirts and cutesy capris on strolls around SoHo. Elsewhere online, fashion content creators and Substack writers with follower counts in the high hundreds of thousands share outfit diaries featuring color-blocked raglan-sleeve shirts from mass retailers like Zara, Cos, Madewell, and Uniqlo’s collab with JW Anderson.
