That... really? That explains the (armor) part of the tag, but then why is it that so many artists draw the same white-haired girl wearing it?
Just look at the thing, its basically a fetish fuel made armor.

Oh and the only thing covering the torso is a tiny jacket with a sash-like cloth around the chest and a loincloth. It's no wonder that this set shows up in Doujinshi material more than any other.
