Kylie wore a long-sleeved red dress with an open back, pairing the dress with strappy heels.
Both Khloe Kardashian and Kendall Jenner wore black, with Kendall throwing on a pair of sunglasses and Khloe looking fitter than ever in a leather minidress.
The celebs attracted a lot of attention from party-goers at Craigs, with people gawking at how good they looked.
Khloe posted an Instagram story of a man flirting with Kourtney and Kim Kardashian.
"You're hot," the inebriated man slurred to the Keeping Up With The Kardashians stars.
"You look like Bradley Cooper," Kourtney can be heard saying to the man.
Larsa Pippen also uploaded pictures and videos from the night on her Instagram.
The Real Housewives of Miami star posted a photo of herself with Kim and Kourtney on Instagram, captioning the photo "Had a blast at my birthday party last night."
The 45-year-old also shared some pictures of herself with the Kardashian sisters on her Instagram story.
Kourtney is especially close with Larsa and could be seen sitting by her side when they sang happy birthday.
Pippen was also a major informant in the drama between Khloe, Tristan Thompson and Jordyn Woods, according to the last episode of KUWTK.
Larsa called Kim Kardashian to tell her that "Tristan was all over Jordyn" the day after he allegedly cheated on Khloe.
