Yeah, it's unfortunate that English lumps everything under "hair". I guess "hair over breasts" is better, though.
By the way, if all you can think of is censoring, you have no sense of eros. This is actually a useful test you can do if you're wondering whether you're erotically retarded. Click that tag and see if your limbic system goes "ZOMG UNCENSOR PLZ".
Actually, I'm afraid "hair over breasts" suggests full covering, which is not necessarily the case. Let's stick with "hair on breasts" for the time being.
