Kendall Jenner and Gigi Hadid Bare Their Abs on a Good Old Fashioned Girls' Night Out—Plus, Kylie's Revealing Outfit

Hollywood's teen royalty brought their style A-game while partying in West Hollywood Thursday night. Kendall Jenner, 20, and a newly single Gigi Hadid proved their BFF status wearing similar graphic T-shirt crop tops, sheer Talbot Runhof wide-leg pants, and black heels. Kendall chose to pair her midriff-baring look with a lacy black bralette and sheer gold flared trousers while Gigi, 21, went with body-con black satin pants featuring plenty of sheer panels.

Both Victoria Secret Angels also opted to finish off their casual looks with simple dewy makeup and low ponytails with face-framing pieces.

Meanwhile Kendall's sis Kylie Jenner chose a much more revealing look for the night out. The 18-year-old wore a figure-hugging nude jumpsuit with strategically placed cutouts, pairing the head-turning ensemble with matching nude suede heels, a diamond Rolex watch, and a statement dark lip. She dressed down the look with relaxed waves and a casual jean jacket.

Looks like it was a fun night out, with Kendall taking to Instagram to post fun scenes from inside The Nice Guy in her "party pants."
