Kim Kardashian may be known for her famous booty, but she made it clear in the Big Apple last week that isn't her only asset.

The 31-year-old reality starlet attended DuJour magazine's launch party in NYC on Sept. 5 wearing a scandalous black-and-white cutout dress. Kardashian flashed major sideboob in the daring, tight cocktail dress that she wore just in time for New York Fashion Week.

Since the Keeping Up With the Kardashians star began dating rapper Kanye West, 35, six months ago, she's changed up her wardrobe. The "Perfect Bitch" singer made a deal with his girlfriend: If she cleaned out her closet, he'd pay for her new wardrobe.

"[You're] getting on best dressed lists now," West said on the E! reality show while admiring Kardashian in a cleavege-baring green gown. "You're stepping into this territory. You look amazing -- it's a new Kim!"
