This year's MET Gala theme had celebrities brainstorming all kinds of eccentric looks to rave the red carpet. The top head-turning gowns showed almost everything there was, with only strategic placing of beads, lace and crystals to hide the sexy parts. Beyonce, Kim and J. Lo took to the carpet in such racy gowns. Rihanna unexpectedly decided to show up fully dressed in a gorgeous yellow robe, a massive creation by Guo Pei that took 2 years to make.
