Kunoichi Fashion Designs

Does anyone have a clue what they call the fishnet underclothes?  Usually, you only see them with kunoichi, usually as some kind of camisole adding some mystery to whatever "cleavage window" their kimono or whatever provides.  But I have seen in movies like "The Magic Serpent" and "5 Element Ninjas" where evidently male ninjas also wear them -- full body-stocking versions, too -- that poke out from under their sleeves and whatnot.
