In non-pornographic anime, TV shows and movies aimed at younger audiences, characters in a state of undress will usually lack certain anatomical features. Such as tear ducts and nostrils. If a female is shown naked from the front, nipples may or may not be drawn. The crotch will almost always be completely featureless, with not even a dark patch to represent pubic hair.
This page is for examples of this in real life, not in media.
- I was with a woman once who had no nipples. She did have areolas, though.
- Sure they weren't just inverted, and thus appeared to not be there? Because while inverted nipples can occur, and are actually somewhat common in some bloodlines, I've never heard of them being completely absent before.
