Cutie Carey Mulligan kicked things off last night at the London Film Festival to promote her movie Never Let Me Go. She provided a fine example of switching things up between day and night, opting for a mustard pleated Proenza Schouler dress with black accents and YSL heels for the photo call, before changing into a black, white and red halter dress from Vionnet’s Spring ’11 collection for the premiere. Her red carpet look was finished off with Giuseppe Zanotti for Vionnet gold wedges. Aside from a bit of a pleats theme, the two looks are really different, with one showcasing her sweet, ladylike style and the other showing more of a fashion-forward approach. I think she looks stunning in both, so now it’s your call. Which look is more fab?
