Kourtney Kardashian hit the town in early celebration for Mama Jenner's 61st birthday ... and while the spotlight should have been on Kris, her eldest daughter seemed to steal that away right quick!
The "Keeping Up With the Kardashians" star opted to flaunt as much skin as possible -- without actually showing much skin -- in a trip to L.A. hotspot, Catch LA. Kourt wore an extremely revealing black lace bra and matching, though more demure, underwear, and simply covered the ensemble up with a transparent, black mesh sheath dress.
She paired nude strappy heels with the look, and kept her makeup natural-looking and her hair long and pin-straight.
Kourtney was the only one of Kris' daughters to show for the b-day dinner, which was also attended by John Legend, Chrissy Teigen, Jonathan Cheban, Simon Huck, Corey Gamble and Scott Disick.
