It looks like some metal gear solid stealth sex dungeon suit
As per the name of the picture, AND the comment attached, that type of fetish suit is called zentai.
Its a bit of stretch (no pun intended) to take it to Spiderman outfits,
and so certainly anything more different (bulky) than a spiderman suit is zentai.
That is, zentair is about a tight fitting suit, and not about lizard costumers or mickey mouse outfits or anything else.
I wonder if it feeds their cleanliness ideals.
