Michelle Williams, one of the finest actresses of her generation, landed her first fashion endorsement and ad campaign -- and it's for Louis Vuitton. That's about as luxe and high-end as one can go when it comes to accessories and apparel brands, so to say that she went "big" her first time out would be a vast understatement.

In the ads for the Fall/Winter 2013 season, Williams hawks two new monogrammed bags: the "W" and the "Capucines."

The images see her signature blonde pixie spilling across her forehead while her scarlet lips scream old Hollywood glam. Understated -- but dramatic. (And to think she was a mousy little thing on 'Dawson's Creek' while Katie Holmes got all the attention.)

Williams' ads, seen below, will first appear in September issues of fashion mags -- the biggest and most fabulous of the editorial calendar year.

“Michelle Williams was selected by Louis Vuitton for her independent spirit with which she has forged her path through Hollywood, defined by her outstanding talent, her passion for her craft, and her choice of daring and challenging roles," the brand gushed about its new spokesmodel in a statement.

She's wearing a Marc Jacobs coat in the first ad here, and that's the "W" bag in both shots.
