We are waiting with baited breath to see who walks the red carpet at tonight's Met Gala honoring the latest Costume Institute exhibition, Manus x Machina: Fashion in an Age of Technology, and more importantly, to see what the attendees are wearing.
In the meantime, let's take a few moments to look back to ten times in recent years that celebrities did not bring their A game to the big night.
It seems foolproof, doesn't it? Beautiful stars dressed by the world's hottest designers, on fashion's biggest night. What could go wrong? Well, unfortunately, plenty it would seem. For every flawless Beyoncé in Givenchy look there is a Kim Kardashian in, well actually, Givenchy, look.
Perhaps it's the stress of knowing Anna Wintour will be there and that she may or may not be judging every outfit. Maybe it's the strain of trying to dress to the theme of the night without looking like you are in costume or possibly it's the stylist's vision that is at fault.
One way or the other, some odd choices have been made by some of the most stylish celebrities out there.
