There’s a production of GROSS INDECENCY: THE THREE TRIALS OF OSCAR WILDE playing now through June 16 at the Abingdon Theatre Arts Complex on West 36th. Have past productions of this play included any nudity? Clearly, they’re trying to imply it with this publicity photo, but who knows if they’ll actually deliver. If anyone sees it, please report! (See link for details.)
MALE NUDITY in NEW YORK STAGE 
The original off-Broadway production did not have nudity. If I remember it correctly, there was a scene in which the actors were wearing underwear of the time period.
