No one parties quite like a Kar-Jenner.
It may feel as though we just finished riding the wave of Kim Kardashian West’s 36th birthday (husband Kanye West’s sentimental video collage will forever claim a place in our heart), two weeks later we’re onto the next one: Ms. Kendall Jenner. Mind you, this isn’t any old birthday—hello, it’s the model’s 21st!
Naturally, Jenner’s L.A. bash was a glamorous, star-studded event, which took place at prohibition-themed hotspot Delilah. Among the many guests seen entering and exiting the party in on-trend duds were Kendall’s sisters Kylie Jenner, Kourtney Kardashian, and Khloé Kardashian, bestie Hailey Baldwin, mother-daughter duo Cindy Crawford and Kaia Gerber, and Kendall’s parents, Kris and Caitlyn Jenner.

The evening’s fashions ranged from subdued and sophisticated (Kris and Caitlyn) to sheer and borderline NSFW (we're looking at you, Kylie). The birthday girl herself wore two separate outfits throughout the evening—though both retained the air of daring that marks most Kar-Jenner outfits.
Scroll through the gallery below to see the best looks from the most stylish guests at Kendall’s awe-inspiring 21st birthday bash.
1. KENDALL JENNER
Jenner kicked off her birthday festivities with dinner at Catch restaurant in West Hollywood, California. For the occasion, the model wore a black Julien Macdonald bodysuit (that gave us major vintage Britney vibes) topped off with a moss green Charlotte Simone stole and lace-up heels.
2. KENDALL JENNER
Cinderella for the evening: Kendall changed costumes during her big night and swapped black bodysuit for this sparkling take on flapper style. She accessorized with a set of see-through sandals à la sister Kim, a L'Afshar clutch, and a silvery choker.
3. HAILEY BALDWIN
Baldwin's first look of the evening (for dinner at Catch) teamed a sheer navy crop top with a set of bulky patterned pants.
4. HAILEY BALDWIN
The 19-year-old model also celebrated her pal's birthday in a club-ready look that included fishnet-style over-the-knee Tamara Mellon boots and a corset-style off-the-shoulder Vera Wang top with Vera Wang shorts.
5. KOURTNEY KARDASHIAN
Kendall's eldest sister arrived at the L.A. hotspot in a shiny silver minidress with hem-lining lace overlays.
