Rosie Huntington-Whiteley took the term "business casual," gave it a twist, and then stepped out like a boss for a CFDA event at Los Angeles's Chateau Marmont on Wednesday.

For the occasion, where the organization's Fashion Fund finalists presented looks on a runway, the 29-year-old beauty donned a pair of wide-leg, pinstripe trousers that featured a high waist, a broad belt, and suit jacket-like layers. She paired the pants with a white button-up, worn partially unbuttoned and off her right shoulder.

Navy pointed-toe heels and oversize black sunnies added to the eye-catching ensemble. Huntington-Whiteley further accessorized with a small black clutch and drop earrings and completed her look with natural makeup and her blonde hair in loose waves.
