Have you tried StyleFeeder? It's a social shopping site -- a giant wishlist for the whole web you can share with your friends. The idea is to highlight your favorite stuff online (Karmaloop, duh), browse your friends' wishlists to see what they like, and rate other people's picks to get recommendations for yourself. Rating and tagging stuff can get pretty addictive, but the best part is finding something you like that you would never have found before. That's how I found Creature Co-Op, for example.
KarmaLoop's own Giovannah has a pretty nice selection, but don't take her word for what's good. See (and rate!) the whole world of jeans, sneakers , hats, and a world of everything else: somebody put an alpaca in there once.
