You'd think that with all the incredible slouchy trousers, high-waisted pants, and gorgeous dresses spilling out of our closets this autumn, we couldn't possibly make room in there for some skirts. Well, you'd be wrong. This fall and winter is definitely a major skirt season with everyone from Phillip Lim and Rag & Bone to Céline and Dries van Noten giving us all manner of versions to literally lust for. Unlike dresses, skirts require a bit more mixing and matching, especially considering the daring lengths that are giving this classic closet staple new life. But given our five categories that are leading the season—knee-length, mini, maxi, full, and pencil—we're positive you'll get plenty of incentive to switch up your pants and jeans routine for something entirely more interesting.
