A Manhattan Federal Court judge did double duty as the fashion police yesterday, when he ordered a groovy balloon artist who's suing police to go change out of his tie-dyed T-shirt, tie-dyed patchwork overalls, and far-out multicolored sneakers. Russian immigrant Alexander "Sasha" Alhovsky, 40, was in the court room during jury selection for the lawsuit, which seeks unspecified damages over claims that the NYPD used excessive force when he was taken into custody in June 2006, on suspicion of planting a fake bomb inside an UES Starbucks three days earlier.
