In America, 21 is the big one. It's the day you're really seen to become an adult and alcohol is officially no longer off the cards in all 50 states.
For model and reality star Kendall Jenner, her 21st birthday was always bound to be a mega-affair, with glittering siblings, a celebrity guestlist and her choice of party venue.
For her evening of revelry, Kendall chose Delilah, a nightclub in West Hollywood, where she dined and danced with friends including best pal Hailey Baldwin.
In terms of her outfit, with probably any of the big labels at her disposal, it's interesting that Kendall chose a slightly lesser known Lebanese designer Antoine Salameh.
According to WWD, the sparkly, backless, chainmail-effect mini-dress was custom made for the younger Jenner girl, as part of his brand LaBourjoisie.
Salameh isn't a total unknown, having previously dressed big stars like Britney Spears, Mariah Carey and Jennifer Lopez.
Hailey Baldwin clearly got the mini-memo, and was sporting hotpants and fishnet thigh-high stockings.
Antoine Salameh's designs are typified by a high-glamour aesthetic - sequins, tassels and sparkles of all kinds are ever present in his clothing.
