In case you missed the internet meme, yesterday was 9/02/10, so of course everyone used it as an excuse to break out their 90s gear and celebrate the kitsch that is Beverly Hills, 90210. There were celebratory parties all around Manhattan, but one of the biggest was the 9021 OH! party at MAD46 Rooftop Lounge.-

Guests proudly showed off their "Donna Martin Graduates" slogans, tucked their bright colored t-shirts into light wash jeans, and asked each other that timeless, all important question: Are you a Brenda, a Donna, or a Kelly?
