She began her career as a model, and judging by her appearance in Hawaii, Charlize Theron still possesses a figure which would be the envy of many a budding style maven. The 38-year-old sizzled in a striped bikini top and black bottoms as she hit the beach on Monday. However, the teeny two-piece appeared to need some adjusting with the actress spotted moving the halterneck into place on several occasions during the afternoon. According to some reports, the star is holidaying with actor Sean Penn and is residing in his beach front property during the trip.
