This season's turn to all things '90s nostalgic has us looking for ways to make that Kurt Cobain aesthetic work beyond the concert venues and the downtown street scene. Think of it as "grown-up grunge," a more sophisticated take on the standout trends that you most closely associate the '90s with - namely plaid, mixed prints, beat-up Converse, ripped denim, and slouchier tied-waist silhouettes. With 3.1 Phillip Lim and Dries van Noten's Spring collections providing serious styling inspiration - OK, we also referenced Saint Laurent's Fall '13 lineup, too - we promise this is a grunge look that even the girlier set will want to try. Click through for three ways to wear it now.
