20-year-old Sofia took to Instagram stories to film her hair and makeup process, before Kylie shared a video of her finished look - a sparkly, silver bra with big '80s hair - saying, “Wow, wow, wow!" as Sofia smiled at the camera.
Kylie then shared a photo of her full outfit, posing beside Kendall in the bathroom. The mother-of-one wore a platinum blonde wig, sparkly pink bodycon dress and sparkly platform heels, while Kendall opted for a shiny leopard print dress with a thigh-high split, straight hair and a red lip.
After heading to the party in a limosine, the famous women shared videos of the inside of the venue, showing disco balls, kareoke microphones and custom cocktails.
While Kendall, Kylie and Sofia enjoyed their night out, Scott is on holiday with his three children and ex partner, Kourtney Kardashian in Costa Rica. Kim Kardashian West and her husband Kanye West are reportedly on the trip as well, with the group filming the new season of Keeping Up with the Kardashians.
