Olivia Culpo, 28, was taking in the nice weather on Oct. 19 and looking great while doing so by wearing an eye-catching black bikini! The brunette beauty posed while showing off a black bikini under a tan, black, red, and white open sweater as she confidently laid on a lounge chair in one snapshot from one of her latest Instagram posts. She paired the look with sunglasses and had her incredibly cute pooch, Oliver, sitting with her in the memorable moment.
