New York - It was a powerhouse of celebrity style that would make a reader of US Weekly jump for joy on Wednesday, October 25th at Bergdorf Goodman's, where the ever-stylish Sienna Miller, superstylist to the stars Rachel Zoe and Vogue's Lauren Davis hosted a dinner party for Marchesa designers Georgina Chapman and Keren Craig.

Marchesa, British design darlings of the Hollywood elite known for their exquisite eveningwear, drew a haute crowd, including "The Devil Wears Prada"'s Anne Hathaway, Padma Lakshmi who has added a stylish presence to Bravo's new "Project Runway" spinoff "Top Chef," designer and Damon Dash's sweetheart, Rachel Roy and model-turned-photographer Helena Christensen.

As if silver screen beauties dressed in dramatic, swoon-inducing gowns weren't enough entertainment for the evening, some added night magic came in the form of hip young magician Alex Ward.
