Before your BFF throws on those ripped fishnets, in an effort to look sexy this V-Day, help her take a cue from the worst offenders on our list. For the most part they've reformed, ditching the "bras=shirts" motto and putting the napkins they were wearing as skirts in the trash. Take notes, ladies, because it's our mission to make sure your girlfriends don't turn out like Xtina this Valentine's Day. Cupid just haaates thong popping jeans.
