At Monday's Met Gala, the stars wore intricate gowns that fit with the night's theme, "China: Through the Looking Glass."
And while it took the stars a few hours to prep for the A-list event, their dresses had been in the works for weeks.
Marchesa designers Georgina Chapman and Keren Craig outfitted Sofia Vergara, Ellie Goulding and Poppy Delevingne for the big evening, as well as themselves.
