BOYS AND GIRLS: It'll be a bachelorette parties dream the next couple of nights at Sidetrack, as the Boystown bar hosts "Night of 100 Drag Queens: 2010 ... A Space Oddity." The event showcases professional and amateur performers in what promises to be a raucous revue. 3349 N. Halsted St, Tickets $15-$25
PROJECT STYLISH: Fashion Focus kicks off tonight with the first of four headlining runway shows. Macy's and CS Magazine present the Chicago Fashion Incubator Designers Past & Present featuring the Spring 2011 collections from 14 designers. Pre-tickets are sold out but a limited number may be available at the door with the after-party scheduled for Market Bar. 7:30 p.m., Millennium Park, Chase Promenade North, 201 E. Randolph St.
MASH FLOB: Every third Thursday of the month the Museum of Contemporary Art turns the concept of a flash mob inside out by giving you a chance to collaborate with professional artists to create participatory "happenings." Join in the fun or sit on the sidelines as a voyeur, which we're guessing is not nearly as much fun. Chicago visual and performance artist Carla Duarte is on tap tonight. 6-7 pm, 220 East Chicago Ave, FREE
