There are a few scenes of bare women's breasts. In many of the versions the shots of longer duration are gone and shadows are used to cover up everything from the just above nipples on down (creative camera work).
There is one scene with skinny dipping of two females. In the more censored versions (again) nipples are not seen and female to female on the lip kisses are removed, and the water and very fast scene cuts make it impossible to any bare flesh of significance. In the less censored versions this is not the case, buit again by today's standards there is no sexuality or nudity of much note.
There is on (implied) sex scene between two major characters. in the more censored version I saw all we got was a shot of Carmilla's face, of her hand grabbing some straw, and a shot of Richard Lestrange's clothed back blocking the rest Carmilla from view.
