What do I name this (ヒトイヌ)? Pool or tag?

What's a good name for the style of bondage tagged ヒトイヌ (hitoinu, "human dog") on Pixiv? The closest English equivalent seems to be "bitchsuit" but that's not quite right since it's not necessarily a single suit.

Also, pool or tag?

Example posts:
post #36833
post #37173
post #45050
post #1483707
post #1600354

Seems gimp_suit has been used to refer to them, though I have next to zero experience with anything bondage related so I have no idea the relevance of the two.

Bondage mittens?
bondage_mittens all_fours search should cover those images.

Tag hcbdsm should be nuked IMHO.

I don't see any mittens in post #45050 or post #1600354.

In any case, the concept is searchable with all_fours bdsm, though admittedly you'll have to sift through a lot of posts to get what you want. I don't necessarily object to a tag for a specific concept like this though.
