When Kourtney Kardashian vacationed in Nayarit, Mexico, she took every opportunity to soak up the sun in her swimsuits. After sharing a snap of herself by the pool, Kourtney was pictured by an outdoor bar wearing yet another sexy bikini. This time around, we got a good look at the back of her white two-piece from Sommer Swim. Her bikini bottom was a cheeky thong, while the top seemed slightly more covered in the front. Though the swimsuit didn't look like it provided too much coverage, Kourtney seemed happy and confident in it. She was smiling as she looked into the camera, and you can tell the star's living her best life right now (Scott who?).
