Forget about the Pussycat Dolls. The Cherry Blossom Cabaret thinks burlesque should stick to its old-school vaudeville roots. But don’t let the vintage feel fool you; these sassy performers put a modern twist on traditional striptease. “What we do is like performance art,” says Lola Love (center). “Our inspiration comes from cabaret, circus, comedy, even drama.” Want to learn how to shimmy? The group teaches a class, Burly-Q Basics, at Mercury Bar. Register for the troupe’s Sept. 13 class ($30, preregistration only) and check out upcoming performances at www.cherryblossomcabaret.com.
