No year is complete without a few crazy fashion trends, and in 2011 there were a few that especially had us scratching our heads. Marc Jacobs sent moonboot-style wedges down his Fall runway, making for a far out, slightly space-age footwear trend. Burberry Prorsum and Christopher Kane showed '60s-inspired plastic and PVC pieces, great for keeping the rain at bay, but still a questionable everyday look. We also saw overstuffed, gorilla-esque fur sleeves at Peter Som and YSL and overtly sexy, undie-baring sheer skirts at Louis Vuitton, Givenchy, and more. Out of all the wacky wardrobe pieces we saw this year, which one was the craziest?
