Aussie cosmetics brand ModelCo welcomed someone new to its family of famous faces. On July 10, British model Rosie Huntington-Whiteley joined Dannii Minogue and Cheyenne Tozzi in ModelCo's stable of brand ambassadors. Rosie was guest of honor at the brand's Black Tie event held at posh Hayman Island on the Great Barrier Reef.

Rosie wears Calvin Klein and Giuseppe Zanotti.

Rosie, who recently shared a Glamour Magazine cover with the boys of One Direction, made sure all eyes were on her as she arrived in all-white Calvin Klein, silver Giuseppe Zanotti heels and a whole lot of ab fab exposure.

Rosie's outfit was all kinds of revealing. A bandeau top showed off her shoulder, arms, and her very toned abs. Her ankle-length skirt did keep her legs under wraps, but she showed off a little more skin thanks to hip cut-outs.

This was an outfit that could easily have gone wrong. But, the top and skirt fit Rosie so well, and her styling was at such a minimum - sexy, beach hair, pink lips, delicate jewelry - that it all worked. And it doesn't hurt that the 26-year-old "Transformers: Dark of the Moon" actress' figure is in great shape.

With a hot modeling career that takes her across the globe, and actor Jason Statham as a boyfriend, Rosie Huntington-Whiteley is no stranger to jaw-dropping red carpet style.

Her Calvin Klein ensemble was not her first outing garbed in daring attire. At the 2013 Met Ball, with its "Punk: Chaos to Couture" theme, the Burberry Body model rocked a sheer, tulle bodice Gucci gown with nothing but strategically placed sequins to cover her up.

When Rosie stepped out with Jason Statham for the "Hummingbird" movie premiere in London, she served legs for days in a tiny Emilio Pucci dress. And it's not only what she shows off, but what she wears that lands her on best dressed lists. When Rosie attended a pre-Oscar dinner hosted by Chanel, she wore a statement-making strapless jumpsuit that was covered in stripes - a bold look few can pull off!
