Kylie Jenner celebrated her 21st birthday on Thursday night, and it goes without saying, it was the party of the year (or maybe the last 21?).

The whole fam stepped out for the bash, including Caitlyn Jenner (who’s reportedly estranged from the Kardashian side of the family).

The birthday girl arrived at the party of a lifetime in a rose-hued satin wrap dress, her long blonde locks secured in a ponytail at the nape of her neck.

Naturally, this wasn’t Jenner’s only look of the night. She later changed into a glitzy body-hugging jumpsuit in a light champagne pink.

Kim followed her little sister’s lead, arriving at the bash in a bubblegum pink minidress with an oval cutout at the waist. She paired the playful frock with a set of purple sandals and a transparent hot pink purse.

The rest of Kylie’s sisters looked similarly fabulous — Khloé arrived in a sequined silver three-piece harkening back to the ‘70s, a newly single Kourtney rocked the ultimate revenge look in a glittering purple minidress, and Kendall showed off her runway-ready limbs in a strapless patent leather LBD.

Natch, Jenner’s stylish sisters weren’t the only celebrities on the scene. Instagram and Snapchat stories from the evening reveal cameos from Travis Scott, Kanye West, Scott Disick, Bella Hadid, Nicki Minaj, Winnie Harlow, Dave Chappelle, Kris Jenner, Corey Gamble, and about a bazillion other VIPs we’re ridiculously jealous of. Guess our invites got lost in the mail, Ky?

Khloé made it clear that she’s hoping for a reunion between Kourtney and the father of her three children, Scott Disick, posting this sneaky video of the couple with the caption “a girl can dream.”

Of course, no birthday party would be complete without the essentials: an insane cake decorated with mini bottles of alcohol and topped with a Barbie clone of the guest of honor, an adult ball pit, and employees wearing t-shirts bearing the host’s most recent magazine cover.

We’ll admit, we’ve never been to a party this extravagant, but we’ve also never met a 21-year-old with a $900 million company to her name …
