Still looking for the perfect party frock for the holidays? The Alice + Olivia by Stacey Bendet Holiday Party (held last night in Hollywood) was full of them. Dozens of celebs, including AnnaLynne McCord, Katharine McPhee, and Ashlee Simpson-Wentz dressed in festive ruffles, sparkle and fur, popped by the shopping soiree, which benefited Baby Buggy, a nonprofit that helps New York City families with small children in need. Here are the looks we're obsessing over.

P.S.: In case you're curious about the Tide bottles sitting on the floor behind the posing celebs (WE WERE!), Tide Free & Gentle (detergent that caters to kids) sponsored the entire event.

KATHARINE MCPHEE: American Idol alum Katherine wore a figure flattering Alice + Olivia "Margaret" strapless sequined dress ($484, bloomingdales.com) under a white furry caplet. We heart the punch of color via her red hot lips.
