Kim's Wardrobe Malfunction.Flashes Underpant At the 2014 Met Gala.

Kim Kardashian experienced a major wardrobe malfunction before hitting the Metropolitan Museum of Art's Costume Institute Gala with fiance Kanye West on Monday, May 5.She unknowingly flashed her dark underwear after her layered custom-designed Lanvin gown -- which included a leg-baring thigh-high slit -- exposed her panties from the side. The incident occurred as she left the Lanvin store with West, after getting fitted for her custom-designed look.

Kardashian's leg-baring Lanvin number also included a thick black belt that cinched her increasingly tiny waist up top. On the red carpet, North West's mommy looked classy and pretty with her glossy brunette locks swept to one side. She also wore a pair of diamond drop earrings by pal, jewelry designer Lorraine Schwartz (who also designed her engagement ring), and rocked black cage sandals by Lanvin.
