Sporting black aviator sunglasses, Jenner sunned herself and showed off her body in a black and white striped two-piece bikini Thursday.
Later that day, she flaunted her sculpted shoulders in a halter-style maxi dress. Kim was also there showing off the results from her 10-pound weight loss and pregnant Kourtney flaunted her baby bump in vibrant bikinis.
Jenner has made it a point to try to keep up with her ageless looks, which is often documented on her family's E! reality TV show, Keeping Up with the Kardashians. In preparation for Kim's wedding in August 2011, Jenner underwent a face lift.
