Celebrities left it all on the Met Gala steps on Sunday: romantic gowns, elaborate but inspiring ensembles, and even golden robot armor. But inside the venue, a few attendees took the opportunity to wear a second outfit just as extravagant as the first. For Met Gala cochair Billie Eilish, who played on this year's "American Fashion" theme with a Marilyn Monroe-inspired ballgown, it only made sense to stick with her Old Hollywood inspiration and change into a wine-colored Oscar de la Renta cape dress.
Like something straight off of a Hollywood red carpet from the 1950s, Billie's dress featured a corset-style bodice, a ruffled hem, and a flowing chiffon skirt with a thigh-high slit that gave us another peek at the tattoo on her right leg. The complementary sheer cape was fastened at the base of her throat with a silver brooch that beautifully matched her jewelry for the evening, and Billie rounded out the look with a red clutch and matching heels.
