Everyone knows the drill for First Fridays. Hit the galleries, nibble on cheese, sip some wine, mix, mingle, and maybe even pick up a piece of art along the way. But DC10 nightclub has a new idea: Fashion First Fridays. Fashion comes first for this new monthly party. Beautiful people and their beautiful clothes should be there in droves; they have hosts from modeling agencies, talent agencies, salons, clothing boutiques, indie designers and entertainment companies all lined up for tonight. (Hit the 3Deep website for the laundry list.) The dress code is "fly, sexy, urban upscale, GQ, high fashion." Got it? Head down tonight for the "models & martinis" mixer for drink specials on cosmos and apple martinis from 9 - 11 p.m. There's no cover, but the line for this hot spot usually gets obnoxious by 11 p.m. Added bonus: If you do brave the early scene, you'll get 20 percent off your bottle service bill for seatings before 10:30 p.m. Go get yourself fly.
