Just when I thought summer skirts had officially run their course as we inch closer towards fall, fashion people found a way to make a new style bubble up in the zeitgist right before the sun sets on the season. Enter the two-tone skirt: a subtle-but-impactful micro-trend that’s quietly taken over some of the chicest wardrobes I follow, from Hailey Bieber to tastemakers summering in the South of France.

Rather than relying on bold prints or statement silhouettes, the two-tone skirt micro-trend is all about contrast. Think bold satin bias-cut slips finished with contrasting lace trim, sheer lace underlays peeking out in an unexpected shade, or clean color-blocking that makes even the simplest midi feel infinitely more interesting. It’s less of a specific skirt style and more of a clever styling detail—and exactly the kind of blink-and-you’ll-miss-it trend fashion people love. Wear it with a t-shirt, a tank-top, or even a cropped trench for chillier days between the seasons.
