While Christina Aguilera steps out in a T-shirt worn as a mini dress, other stars are showing just as much leg but in a more glammed up way.

Model and Transformers 3 actress Rosie Huntington-Whiteley first made the sexy look her own when she stepped out in several floor-length evening gowns with thigh-grazing slits by Michael Kors, Stella McCartney, Burberry and Antonio Berardi this past summer. (Here, she's in Valentino in Hollywood Feb. 27).

At the big reveal for the Victoria's Secret Fantasy Bra in NYC on Wednesday, Miranda Kerr, the Angel who's been tapped to wear the $2.5 million creation, chose a fuchsia Michael Kors strapless number, which she paired with gold triple strap sandals, also by the designer.

Amber Heard added even more length to her legs in nude Christian Louboutin platform pumps, which she wore with a red-hot Elie Saab gown at a film premiere in Los Angeles October 13.

Since all three slim-bodied beauties have supermodel status and tower over their peers (Heard is 5-foot-8 while Huntington-Whiteley and Kerr are both 5-foot-9), it's no wonder that this flirtatious style works on them so well.
