Kendall Jenner's Birthday Jumpsuit Leaves Little To The Imagination

Talk about a birthday suit!

To ring in her 20th, Kendall Jenner stepped out at The Nice Guy in Hollywood donning one of her sexiest ensembles yet: a barely-there jumpsuit by Sergio Hudson.

The custom-made piece featured a plunging neckline, daringly low back and mesh panels. The bottom portion featured a wide, flared leg, to balance out the revealing top.

For her beauty look, the Victoria's Secret Fashion Show model opted for a messy topknot, bright red lips and simple eye makeup. She accessorized her ensemble with a black, patent leather belt, a small black wristlet and black heeled sandals.

The brunette beauty celebrated with family and friends, including mom Kris Jenner, big sisters Kourtney and Khloe Kardashian, Kim Kardashian and hubby Kanye West, little sister Kylie Jenner, and model besties Gigi Hadid and Hailey Baldwin.

The star-studded celebration also included Justin Bieber, Drake, Tyga, Nick Jonas, Ruby Rose and Jaden Smith, all of whom posed for shots in a photo booth -- a Kardashian-Jenner tradition.
