The Cold Shoulder

If one trend was apparent at Monday night's Costume Institute Ball (besides that mere mortals had no chance of playing with the superheroes) it was this: the one shoulder dress is back... big time! In an array of fabrics, colors and lengths, it was THE look of the night, you know, if you weren't going for that whole Wonder Woman thing. Here, some picks:

Clockwise from top left: Camilla Belle in Armani Prive, Claudia Schiffer in (and with) Valentino, Emily Mortimer, Fergie in Calvin Klein Collection, J. Lo in Alberta Ferretti, Eugenia Silva in Armani Prive

Clockwise from top left: Karolina Kurkova in Vera Wang, Kate Mara in Zac Posen, Michelle Tractenberg in a vintage skirt and top, Sara Larson and George Clooney - both in Armani, Michelle Monaghan in J. Mendel, and Lauren Bush and David Lauren - both in Ralph Lauren

Even the designers themselves gave the cold shoulder with Diane von Furstenberg and Stella McCartney each wearing their own designs and Tory Burch wearing Proenza Schouler.
