Style Battle: Leighton Meester and Kate Bosworth in Proenza Schouler Dresses

by Brittney Stephens 0

When it comes to stylish celebs in designer dresses, there's always going to be one lady who comes out on top. Last night at a Nylon Magazine party in her honor, Leighton Meester rose to the occasion in a colorful frock from Proenza Schouler's Spring 2011 collection — much like the one that Kate Bosworth wore to the 27th annual Night of Stars event last October. Leighton went for a silky, sexy approach while Kate opted for the ladylike short-sleeved number. Both ladies lit up the room in Proenza's neon creations, but we're dying to know — whose look was most Fab?
