"I've always wanted to have a frat party," Alexander Wang told us last night at his Animal House–worthy rager at Pier 40. Guests were greeted with glow sticks, jello shots, and fridges packed with 40's of Bud. In the back, people played beer pong, ate burgers and hot dogs, and did keg stands. The walls were plastered with vintage Playboy centerfolds and TVs were set up to play sponsor Sony PlayStation's new game Everybody Dance. Wang challenged actress Christina Ricci to a game. His song choice? Rihanna's "Rude Boy." (Ricci won.) "I always play [the game] with friends and I let them choose the songs because I'm way too embarrassed to be like,' I want to dance to the New Kids,'" Ricci said, while perched on a shabby sofa. "I've never been to a frat party. This is my frat party."

Ricci, who stars in the new TV series Pan Am, says that she's always been a fan of the era. "I've always been a big vintage shopper and the sixties were my period," she told the Cut. "It's the cut that looks good on me. It's very feminine and has a sense of fun and a sense of humor about it. It's kind of an ideal thing for me. Now my job is to dress up in sixties fashion." Maybe Ricci's affinity for all things sixties runs in the family: Her mom was a mod fashion model, after all. "That has a huge influence on me as well. My first images of beauty were images of her fashion tear sheets," she added. But shooting the show isn't just about playing dress up: Ricci is terrified of being filmed in high-definition. How is she coping? "Sleep as much as possible, intensify the face cream and I'm getting a prescription for Retin-A," she told us. "The rest is out of my hands."
