Getty ImagesFashion faux pas doesn't even begin to cover this nightmare.
Don't get us wrong—the worst dressed stars ever are just as breathtaking as the best dressed stunners. It's just that they're breathtaking for all the wrong reasons. Case in point: Laetitia Casta. Back in 2013, the actress was ready to take flight in a golden wing draped gown with a bizarre sheer floral stripe. Think that's bad? It only gets worse from here.
Larisa Katz: We have only one thing to say to you. Why?! This voluminous contraption is beyond comprehension, and looks like something à la Lady Gaga's wardrobe. And Elena Lenina has worn many an over the top design to the Cannes Film Festival, but this teal gown and sky-high hairdo reached a new level of wacky.
Florence Welch also had a regrettable mishap in a pink polka-dotted Miu Miu nightgown design. And last but not least, Björk—well, at least that poufy cotton candy confection is better than the swan dress!
And that's not all—check out even more Cannes catastrophes in the gallery below!
