The 2012 BET Awards went down last night in L.A. -- and there were some big fashion hits and misses!
Kim Kardashian showed up with date Kanye West wearing a sexy white dress with a plunging back ... and while it looked amazing on her, it also looked very similar to the backless white dress former "America's Next Top Model" winner Eva Marcille was also wearing. Whoopsies!
Kim and Kanye had great seats for the show -- sitting front row next to Kanye's good friend and collaborator Jay-Z and wife Beyonce Knowles, marking the second time Kim & Beyonce have been seen hanging out together in the past two weeks.
Bey was looking sexy in a yellow gown with a slit up the side.
Mariah Carey hit the stage at the event as well, showing off her thinner frame in a bedazzled nude number that clung to her newly-thinner frame.
Of course, not all the fashion was good.
Check out the gallery above to see which stars looked great ... and who really should have gone back into their closet before hitting the red carpet.
