Alexa Chung & Joan Smalls Join Poppy Delevingne In Celebrating Her Solid & Striped Collaboration Launch

Leave it to our other favorite Delevingne to host a chic swimsuit collab launch at one of NYC's most buzzed-about new spots, The Happiest Hour. While Cara wasn't in sight to help celebrate Poppy Delevingne's new line with Solid & Striped, there were plenty of It Girls around to make sure the soirée was a stylish one. Alexa Chung, Joan Smalls, and Harley Viera-Newton were just some of Poppy's BFFs in attendance, and when that group gets together, there's sure to be plenty of fun photos.
