Ah, the MTV Movie Awards — it’s where best kiss dreams are made (Selma and Sarah, Rachel and Ryan), epic stunts and speeches are performed, and fashion all but takes over the show. That’s because when it comes to MTV, stars show up wearing anything — and we do mean ANYTHING — they want, and the results are nothing short of eye-popping.

From Christina Aguilera’s Moulin Rouge-era lion’s mane and bustier to Katy Perry’s bright blue wig, it’s thrilling to speculate on who will show up wearing the year’s most insane outfit. In honor of Sunday’s show, take a look back at the absolute craziest looks yet below.
