Unzipped (Cinemax early Wednesday at 5:15 a.m.) Douglas Keeve’s 1995 documentary is an affectionate portrait of major fashion designer Isaac Mizrahi as he prepares his Fall 1994 collection, meant to be a comeback after a couple of off-years. Mizrahi emerges as an enormously likable man, witty, bright, a terrific mime but rightly tough and decisive when it counts.
