This season’s catwalks schooled us in cool co-ed style. The lesson? Break stereotypes with bold mash-ups of color and texture. Versace executed this to perfection with a Cluelesschic parade of mismatched tartan looks. Or take a note from Coach and pair a shiny gold midi with a rugged cable-knit sweater for off-campus appeal. Other smart ideas: miniskirts in menswear-inspired fabrics (team them with matching jackets à la Dior, Miu Miu, and Prada), crisply tailored trousers, and Blair Waldorf– worthy headbands. Now repeat after us: Does this come in plaid?
