Kourtney Kardashian goes super retro in latest poolside snap

Summer might be over, but Kourtney Kardashian is still showing us how to be bikini chic in September.

Over in Calabasas, the 40-year-old Poosh founder hosted an end-of-summer wellness event for her lifestyle brand in her backyard. While guests enjoyed custom Stuart Weitzman sneakers, free Onia Swimsuits and Brooklinen robes, they were also treated a Gymshark yoga class led by Melissa Alcantara and facials that were set up on Kourt's basketball court. Dreamy, we know.

Rosie Huntington-Whiteley, Suki Waterhouse, Malika Haqq were just a few of the star-studded guest who stopped by the intimate event.
