Rihanna has had a busy week! After releasing the music video for her new single, "Where Have You Been," the pop star jetted off to Hawaii,  where she chose to unwind in two sexy fringed bikinis. She worked a L*SPace black "Dolly"  bandeau top ($68 at amazon.com) with matching "Monique" bottoms ($68 at freepeople.com) while splashing around in the Hawaiian waves, and later changed into Acacia's tie dye "Montauk" style ($184 at butterfliesandbikinis.com), switching out the bikini's bottoms for the brand's crocheted "Seminyak" pair ($96 at sirenecollection.com).
