Why We Love It: Bust out your Doc Martens and plaid because the '90s are back, and we couldn't be happier! But we're not rehashing Courtney Love's Garbage band days here. For Fall 2010, the look is cleaned up with gorgeous materials giving the trend a posh twinge.

Pair It With: For an easy everyday street grunge vibe, grab some distressed jeans, a flannel top, oversized slouchy beanie and don't forget your combat boots! Balance the look with a feminine touch by combining floral sheer tights and a lace bralet with harsher '90s-inspired pieces like destroyed cut offs.
