After launching the new range of Kardashian-Jenner apps earlier in the day, the mother-of-three switched her whimsical, cream outfit for a daring black ensemble.
Doesn't she look amazing?!
The 36-year-old flashed her midriff in a black boob tube and skintight leather trousers, finishing her look with a casual jacket and heels.
We're having major hair envy thanks to those poker straight, glossy black locks, while her make-up was flawless. Obvs. She's a Kardashian!
Earlier in the day, the eldest of the Kardashian-Jenner clan had been at the Apple Store Soho with sisters Kim, Khloe, Kendall and Kylie to preview their brand new apps.
Each sister is launching her own app focused on the things that matter to them the most. For Kourtney, that's being a mother, so her app will feature lots of content relating to life as a mum to three children.
She shares sons Mason, five, and Reign, nine months, and daughter Penelope, three, with ex-boyfriend Scott Disick. They split in July after nine years together.
