With the amount of red carpets and events that celebrities attend, and the number of celebrities, there are bound to be some repeat outfits.
In today's "Style Showdown," we want to know who wore this Zac Posen A/W10 frock best. Was it Kelly Osbourne at the Teen Vogue Young Hollywood Party or Rose Byrne at the premiere of Get Him to the Greek earlier this year?
Both accessorized with clutches and great shoes, but Byrne also opted for a belt.
Comment and let us know who you think wore it best.
