The Rodarte sisters, Laura and Kate Mulleavy, cohosted a special dinner last night with Kate Bosworth at the Harvey Nichols Fifth Floor restaurant in London. Of her peach silk and net Rodarte dress, Kate Bosworth said: "It's kind of deconstructed ballerina." If Kate was a deconstructed ballerina, then actress Emma Watson was a rebel dancer in her bold black, blue, and white Rodarte frock. Both stars wore Rodarte's Spring frocks beautifully, but only one can win this battle. Who's it gonna be?
