One of the easiest ways to take an ensemble to the next level is with intentional layering. And come winter, this style hack materializes as simple white tees under sweaters. That said, this season is eliciting a different response, with fashion people swapping their classic white T-shirts under their sweaters for ones in an array of hues, from primary colors to black.

One could argue that fashion insiders may have been influenced by Celine’s S/S 2026 and resort collections, spearheaded by new creative director Michael Rider. The runway looks fused Parisian-chic silhouettes with '60s-inspired designs, boasting bright pops of cherry red, Kelly green, and sky blue. Most notably, many sweaters were layered over vibrant silhouettes, offering peek-a-boo bursts of color, executed in a subtle and elevated way.

Now, It girls are trading in their predictable ensembles for the designer-endorsed combo—and you’ll want to take notes. So, whether you’re after a striking set of avocado green and azure blue or a subtle balance of dim gray and midnight black, this layering trend is for you. Scroll to shop chic combinations.
