Last week, the CFDA/Vogue Fashion Fund dinner celebrated up-and-comers in the style biz, and our eyes were glued to the attendees. Two sartorial stand-outs: Jessica Stam and Mia Wasikowska. While Stam went sleek and sexy (and set the standard for how to wear pants, this season!) in Band of Outsiders and Fallon, Mia kept it feminine and flirty in a purple Rodarte dress. Which look do you prefer? Vote below and let the chic war begin!
