Ever since she was signed up as the face of Balenciaga's new fragrance, Kristen Stewart has been on a style trajectory. First came the front row seats at Paris Fashion Week followed by the killer Balenciaga gear and now that the promotional tour for (deep breath) The Twilight Saga: Breaking Dawn Part II is upon us, K-Stew has well and truly got her sartorial mojo sorted.

Kristen's most recent red carpet hit came last night when she attended the LA premiere of On The Road wearing a menswear-inspired jumpsuit. The ensemble comes courtesy of Balenciaga, naturallement, and is hot off the French fashion house's Spring 2013 catwalk. It consists of a white criss-cross bustier top teamed with classic high-waist black trousers, topped off with Christian Louboutin's Décolleté heels plus a ponytail twisted to one side. We have three words: ah.may.zing.

How far she's come! Kristen in 2008 vs 2012

This is further proof that Kristen is more comfortable with her fashion credentials than ever before. She's escaped her style rut of embellished mini-dresses and found a niche without compromising on that edgy aesthetic. Remember the gawky, surly teen who stomped onto the red carpet to promote little-known-film Twilight way back in 2008? You'd hardly believe it was the same girl who looked postively radiant at last night's shindig, confidently striking a pose and flashing her abs with lashings of attitude. How far she's come, eh? It seems that at last K-Stew is playing the fashion game and (SHOCK) enjoying it.

This winning look follows an appearance for Twilight at the Four Seasons Hotel, which saw the actress donning a sexy black and green dress. The optical illusion design makes her look more shapely and womanly than ever, again suggesting that tomboy K-Stew is finally embracing her smokin' hot body, not to mention the world of high fashion. May her style ascent continue!
