Carey Mulligan selected look from Peter Pilotto’s Spring 2011 collection to wear to the Los Angeles Times ‘Young Hollywood’ Roundtable event back in November.

The darling young actress wore a slightly modified version of the dreamy chiffon dress, as her version features a shorter, fully printed lower half.

Carey kept things simple and only added a pair of blue satin peep-toe heels to her look. She wore her makeup light and wore her hair in a loosely pulled back bun.

Last week Samantha Cameron also wore the same modified version of the dress to meet President Obama and wife Michelle Obama on the steps of 10 Downing Street.

Also keeping her look minimal, Samantha added a pair of grey platform heels to the dress. She wore her down and straight and kept her makeup light.

Although both women look great in the dress, I’m voting for Carey on this one.

I love her cool but casual hairstyle and think the dress suits her eclectic style more. She brings a bit more attitude to the look than Samantha.
