The Met Gala is pretty much fashion with a capital F. So when the theme is the work of Commes de Garcon founder Rei Kawakubo, the ante is officially upped. Significantly. Known for her cerebral take on fashion, Kawakubo is no stranger to out-there styles that read more catwalk than red carpet. Which is why we couldn鈥檛 wait to see what the celebs pulled out for this year鈥檚 fashion prom. Take a look at some of our fave celebrities on the red carpet tonight, who had us doing a major double take.

1. Katy Perry: Never missing an opportunity to show her flair for the dramatic, gala co-chair Katy Perry showed up in layers of red tulle, complete with a veil and space-age 鈥淲itness鈥 headpiece. (Photo via Dimitrios Kambouris/Getty)

2. Allison Williams: We literally scrolled past Allison Williams鈥 picture without realizing it was her. New hair, who dis? (Photo via John Shearer/Getty)

3. Rose Byrne: Speaking of hair, Rose Byrne kept it interesting with lots of volume and enough curls to counter her typically wavy 鈥榙o. (Photo via Karwai Tang/WireImage)
