Caitlyn Jenner met up with Kourtney Kardashian and Kylie Jenner on Thursday night at Nobu in Malibu, and the ladies were all dressed to the nines. (Kylie's much older boyfriend Tyga was there too, but unless he's singing about "penetrating" the 18-year-old reality starlet, we don't really care much about him...)

Kourtney looked incredible, and while Kylie's outfit was like something from the Clueless era, she looked pretty hot too. Caitlyn rocked a super chic black outfit, and we couldn't help but notice how slender her 6'2" frame is looking these days. Apparently Kylie was proud of her dad's look. She posted this cute selfie on Instagram:
