The sisters have been attending the Met Gala since they were freshmen at NYU, and always manage to steal the show.
The sisters attended their first Met Gala at 18. The theme was “The House of Chanel,” but Ashley wore Oscar de la Renta, while Mary-Kate opted for vintage.
For the “AngloMania”-themed exhibit, the pair wore Badgley Mischka.
That year, the theme was “Poiret: King of Fashion,” and the pair walked separately. Mary-Kate wore a black feathered gown from Lily Et Cie by Rita Warnick.
Ashley Olsen, meanwhile, contrasted in a white gown fit for a Grecian goddess.
For the “Superheroes” edition, the Olsen twins wore Diane Von Furstenberg gowns with Louboutin heels.
For “The Model as Muse” theme, Mary-Kate Olsen wore vintage Christian Lacroix.
Ashley Olsen, meanwhile, opted to wear a gown from their own brand, The Row.
After a year off, Ashley Olsen returned in 2011 in a Dior gown for the Alexander McQueen-themed exhibit.
In a rare embrace of color, Mary-Kate Olsen went for a fiery red Givenchy gown.
Mary-Kate came solo for the “Schiaparelli and Prada: Impossible Conversations” exhibit, and wore The Row.
Although the theme was “Punk,” Ashley once again opted for Dior, this time in a soft orange.
Mary-Kate wore vintage Chanel couture while carrying a Balmain coat.
The twins returned to walking together in 2014. They both wore vintage, from Chanel and Gianfranco Ferré.
The theme was “China: Through the Looking Glass,” but the Olsen sisters both opted for black vintage numbers from John Galliano’s run at Dior.
The theme was “Manus x Machina” and the sisters wore vintage that seems to have never been properly identified.
Once again, the sisters wore outfits from so deep inside their vintage collections that the designers weren’t publicly identified.
For the “Heavenly Bodies” exhibit, Ashley’s metallic gown was vintage Paco Rabanne. Mary-Kate’s black dress was from The Row.
For the “Notes on Camp” Met Gala, the sisters once again opted to coordinate in vintage leather looks from Chanel.
