(BURLESQUE) The weekly pinups-and-pillow-fights night slinks out of the Underground and onto the main stage of the Fenix for an extra special expo of the city’s most sophisticated ecdysiasts—Tamara the Trapeze Lady, Burning Hearts, the Von Foxies, and a dozen other cheeky lasses shakin’ their asses. (Fenix, 109 S Washington St, 405-4323. 8 pm, ladies free, guys $7, 21+.)
