Michelle Williams rocks sexy LBD at film premiere in New York

The actress dazzled in a black Altuzarra dress at the New York premiere of Take This Waltz

We're more used to seeing Michelle Williams looking all sweet and demure on the red carpet, but last night the actress went for full-on sexy in a little black dress at the premiere of her latest film in New York.

The pretty starlet attended the screening of Take This Waltz at the city's Landmark Sunshine Cinema wearing a black midi-length cocktail dress by Parisian designer Joseph Altuzarra from his eponymous label's resort 2013 collection.

And in a new style direction for Michelle, the dress featured a sexy plunging neckline, which showed off her cleavage, with leather criss-cross straps and tassels decorating the front.

As for the accessories, the blonde star completed her look with a pair of simple white Givenchy sandals, a diamond heart-shaped pendant by Jade Trau for Forevermark and a black sparkly Judith Leiber clutch.

Looking content and happy (maybe new boyfriend Jason Segel has something to do with it!), Michelle giggled and smiled her way through the premiere press photo session alongside Take This Waltz co-star Luke Kirby and director Sarah Polley.
