Mary-Kate Olsen is being named the worst dressed actress to appear at the Metropolitan Museum of Art Costume Institute Gala in New York on Monday, May 5th.

Apparently Mary-Kate didn’t get the memo that the fashion Gala was not an actual costume party. Many other A-list celebrities dressed to perfection attended the event.

The Gala was held in honor of the museums new exhibit Superheroes: Fashion and Fantasy. The exhibit will be at the Metropolitan Museum of Costume Art Institute from May 7th to September 1st.

Take a look at the photos of the other fashionable celebrities below.

So what do you think does Mary-Kate need to fire her stylist? I think that she is by far one of the worst dressed celebrities in Hollywood.
