Jessica Alba in Lanvin | Paris Fashion Week: Fall 2012 – Lanvin 10th Anniversary Runway Show

Jessica Alba took to Paris this week to enjoy some of the runway presentations during Paris Fashion Week, including the Lanvin fashion show last night. This event marked the 10 year anniversary of Lanvin‘s runway show, and there was a pre-party for designer Alber Elbaz held at Halle Freyssinet the same night with a giant cake!

The 30-year-old actress was decked out in head-to-toe Lanvin! She wore a stunning two–tone one-shoulder techno stretch cocktail dress with crystal serpent detailing from the Spring 2012 collection that she paired with solid black pumps.

The bordering crystal detailing is beyond gorgeous, but I wish she had worn the belt seen on the runway.

With dramatic eyes and dark red lacquered nails, Jessica wore her hair up and finished her look of with a navy blue lacquered “Sea Breeze” minaudière and a blue crystal cocktail ring from the collection.
