There's no full female nudity in the movie. Angel's hair and arms are often strategically placed to hide her nipples. In several scenes, she has simple implied nudity. We do see her breasts slightly from the side on one or two occasions but nothing overly graphic.
The prostitutes in the brothel show cleavage and wear short undergarments with stockings and garters.
Several implied sex scenes between a prostitute and her clients, but nothing is ever graphically shown
While it is implied Angel is nude she is only seen from the back and waist up.
Angel and Michael have sex on top of a mountain, fully clothed. She is seen straddling him and thrusting. No nudity.
This movie was very steamy, while not graphic in terms of nudity, it was sensual. There were two sex scenes. A lot of sounds, facial expressions, movements that left very little up the imagination.
There is no "technical" nudity in this film (nipples showing), but the film leaves little to the imagination when it comes to Angel's body.
