Rosie Huntington-Whiteley was at the Costume Institute Gala exhibition on May 6.
Rosie managed to work the "punk" theme while also going for what works for her, in a black-and-gold Gucci gown that featured one of her fave cleavage-revealing cuts.
Completing the look were a lizard-skin Broadway clutch with fab bejeweled clasp, and Lorraine Schwartz jewels.
