'Twilight' Star Kristen Stewart’s Stunning Retro Looks

Evolving from a shy Bella Swan in the Twilight saga to a glamorous star, Kristen Stewart has emerged as a fashion icon and a very stylish woman.

The 21-year-old actress from Los Angeles attempted to bring back old-school glamour when she posed in a retro-style bikini for the cover of GQ.

The star, who almost always preferred a tomboyish look in the past, underwent a sudden transformation, following her growing popularity.

Going all vintage for the new cover, Stewart surprised everyone with her sensual makeover. Donning a 60s-era hairstyle and the appropriate makeup, the Twilight star spoke to GQ about her sudden transformation.

I looked like a boy for a long time. Now I feel like a woman, GQ quoted Kristen as saying.

However, her more mature looks are not surprising, considering her gradual role transformation in the new series of the Twilight saga - Breaking Dawn: Part 1, to be released Nov. 18.

The recently released theatrical trailer shows Stewart's transformation, from a shy schoolgirl to the wife of a vampire and then to a mother.

Outside the Twilight universe, Stewart is also working on another new movie, Snow White and the Huntsman, which is a modern version of the classic fairy tale.
