On Wednesday night, the Poosh founder stepped out for her younger sister Kylie Jenner's launch of new Kylie Lip Kits at Ulta in Los Angeles dressed in her signature head-to-toe black. On top, she wore a black leather, studded bustier layered underneath a cropped cardigan shrug, and on bottom, a pair of baggy black pants flowed over her towering heels. Getty While Kourtney's outfit was a nod to the early '00s, her hairstyle, on the other hand, threw it back to a whole other decade. Ditching her bob for long extensions for the evening, Kardashian scraped back her dark brunette tresses into a '90s-inspired high ponytail with a sleek, side part and a section of straightened hair left loose. @kourtneykardash/Instagram Everything About Kourtney Kardashian's Bubblegum Pink Trench Coat Screams Barbiecore In addition to Kourtney's goth-glam look, the Kardashian-Jenner sisters brought their own distinct styles to the party. Kim showed up in a backless, skintight bodysuit paired with a tiny Balenciaga bag and thigh-high boots, and Kendall expertly toed the line between retro and modern in a strapless dress with a cyborg on the front accented by a leopard-print balconette bra. Khloé, for her part, went full-on Barbiecore in a hot pink suit, while the lady of the hour, Kylie, teamed her little white dress with statement sunglasses.
