Kendall Jenner celebrated Memorial Day weekend exactly how you might expect — lounging poolside [1] with her sister, Kourtney Kardashian, and a few members of her intimate circle of friends. Of course, the 22-year-old model dressed accordingly, too. Kendall paired a patriotic red-and-blue bikini top from Solid & Striped with a quintessentially '80s high-cut bikini bottom. Kendall is one of many celebrities to sport a suit from the trendy swimwear brand, including Olivia Wilde [2], Gabrielle Union [3], and Demi Lovato [4]. The pool party also featured nostalgic water soakers and some Funboy Fun Ski [5] pool floats. Ahead, shop Kendall's bikini and similar primary-colour cuties.
