Mary-Kate and Ashley Olsen were fashion pioneers well before they started their own high-end label The Row in 2006 (lest we forget their first fashion line, sold at Walmart). While the Met Gala is now known as the Oscars of Fashion, minus the awards, the event has been a yearly happening since 1948. No, the twin sisters haven't been going since the '40s, but they've have been frequent Met Gala guests since the mid-aughts. Before there was Rihanna and Kim Kardashian West, there was Mary-Kate and Ashley Olsen.
They have been on the coveted guest list since 2005, and their 15-year sartorial evolution is well-documented in the annals of Getty Images and weird Vogue videos. From their NYU-attending, Starbucks-wielding, hobo-chic days to their current style of high fashion vintage, the two have come a long way, with an apparent pit stop to the tanning salon in 2006. (It was 2006!)
Save for one year of reprieve in 2010 and one absence by Ashley in 2012, the Olsens have been a red carpet staple at the annual fashion event. While there may be no Met Gala on May 4 this year, it's safe to assume Mary-Kate and Ashley would have been there, come hell or high water. To honor their dedication, we've rounded up all their Met Gala looks, below.
Mary-Kate & Ashley Olsen at the 2005 Met Gala
Still in their New York Minute hairstyle era, the two made their first Met Gala appearance in 2005 for the The House of Chanel exhibit. Despite the theme, Ashley opted for an Oscar de la Renta gown while Mary-Kate wore vintage.
Mary-Kate & Ashley Olsen at the 2006 Met Gala
Mary-Kate and Ashley wore Badgley Mischka to the 2006 Met Gala, dubbed AngloMania. While some attendees opted for their best tartan plaid and British punk ensembles, the two arrived in unexpectedly sophisticated (and tanned) looks.
"These were custom looks, so we went through fabrics together and they gave us an idea of what they liked," designers Mark Badgley and James Mischka told Page Six in 2018. "This was around the time that they were always photographed running around with their Starbucks, so it was fun to glam them up."
Mary-Kate & Ashley Olsen at the 2007 Met Gala
In 2007, the Met Gala honored historic French designer Paul Poiret, and Mary-Kate wore a dramatic feathered gown from Lily Et Cie by Rita Warnick.
Ashley went in a different direction, wearing a simple white gown with a mink stole.
Mary-Kate & Ashley Olsen at the 2008 Met Gala
