If you didn't know, the Met Gala is an annual event held at New York's Metropolitan Museum of Art to celebrate fashion and raise money for the Met's Costume Institute. This year's gala is on Monday, 7 May.
Since it's one of the ~biggest nights in fashion~, we thought it'd be fun to take a trip down memory lane to the superhero-themed 2008 Gala. Here's who went and what they wore...
Mary-Kate and Ashley Olsen with Christian Louboutin
Blake Lively and Penn Badgley
Donald and Melania Trump
Ivanka Trump with Gilles Mendel of J. Mendel
George Clooney and Julia Roberts with Giorgio Armani
