When Chanel throws a party, we always expect a bevy of beauties, decked out in Chanel, of course, to follow suit. Last night, the brand hosted an 80th anniversary party for its Bijoux de Diamants collection in NYC, attended by the likes of newlywed Blake Lively  — who coyly hid her left hand in her pocket last night — wearing a silver halter-neck dress, Diane Kruger  in a shimmery blue strapless number, and Alexa Chung looking ladylike as ever in a floral-embellished beige dress. It was all about ladylike glamour, further exemplified by January Jones 's chic black and white gown, Leigh Lezark's laced confection, and Linda Evangelista's smart tweed two-piece. Take a look at all of the gorgeous ensembles from last night's party, and tell us which one is your favorite.
