Jessica Alba [1] showed off her fit figure in a black Mikoh one-piece [2] while vacationing in Hawaii on Wednesday. The actress and Honest Company founder hit the beach in her sexy swimsuit and a matching baseball cap and held on to a pink one while heading out of the ocean. It's likely that Jessica and her family [3] made their way to Hawaii after celebrating Christmas; on Sunday, she shared a cute Instagram snap of her and husband Cash Warren in matching PJs [4], writing, "We had an awesome Xmas." The last time we got a glimpse of Jessica's banging body was back in July when she ushered in Summer with a cute pineapple-print bikini [5].
