Jessica Szohr, Mary-Kate & Ashley Olsen and Celebrities at the WWD Gala

The fashion, celeb and beauty worlds joined forces in NYC last night to help WWD celebrate a milestone: turning 100 in style! Which is no mean feat!

Amongst the crème de la crème  of design talent was Gossip Girl's Jessica Szohr, who was a regular at NYFW, the Olsens who both went for shockingly similar hair and makeup styles, gorgeous redhead Karon Elson (who hasn't said much about stealing Christina Hendricks' look), Aussie model Nicole Trunfio, shoe-queen-turned-fragrance-designer Tamara Mellon and Rimmel London model Coco Rocha.

Check out all the glitz and glam from the evening right about now . . .
