This year?s Met Gala was inspired by the Metropolitan Museum of Art?s ?Heavenly Bodies? exhibit. Invited guests came fully dressed to theme, all taking different takes on it. One guest came looking like an angel, wearing a literal halo: Rosie Huntington-Whiteley. The model and actress wore a caped Ralph Lauren gown resembling stained glass windows. But what caught everyone?s attention was her halo clipped onto a knotted bun with a sleek middle part.
