Though she's new to film, Rosie Huntington-Whiteley has the red-carpet skills of a seasoned pro. The English model-turned-actress may be best known for her sultry turns down the Victoria's Secret catwalk, but with Transformers: Dark of the Moon now under her belt, we can only expect to see more of the 24-year-old head-turner. Red-carpet weapons include gorgeous, curve-hugging gowns; Burberry, Versace, and Michael Kors are favorites. Of course, the deal clincher for us may just have been the sheer Gucci we caught her in at last week's premiere. She seems to have mastered the art of balancing glamour and sophistication, which isn't always a sure thing. Click through to see Rosie's standout red-carpet moments, aka a how-to in knocking 'em dead every time.
