Just when you thought you had all your holiday shopping in the bag, you check your calendar and suddenly remember Christmas isn't the only important date that's about to sneak up on us all! New Year's Eve is yet another occasion that makes fashionistas hit the stores even more than usual, because even if you have a closetful of cocktail attire, the desire to go glitzy and glamorous seems to renderall the frocks you already have unsuitable. But good news -- there are plenty of party-friendly sheaths that won't have you drowning in debt (especially in the wake of splurging on Christmas gifts), whether your NYE plans call for a classy cocktail dress or a sexy Herve Leger-inspired number. And the best part? The winter season's sequin fetish will guarantee your dress won't be obsolete even after the 2010 ball drops! Check out the slideshow for my 10 favorite picks.
