Invisible transmog items

[Yoruko]

I'm trying to make a list of items that cause pieces of armour to become "invisible" when transmogged. Any help and contributions to the thread would be greatly appreciated! I will only list items that are currently allowed to transmog for the sake of clarity.

Cloaks:
"The Emperor's New Cape" - Usable by all | Obtainable by all

Belts:
"Acherus Knight's Girdle" - Plate | Only obtainable by Death Knights

---

Partially invisible or invisible on certain races:

"Tsunami Boots" - Mail | Obtainable by all | Invisible boots for draenei, tauren, trolls, worgen (Thank you Vephriel!)

that's pretty much it, there is a leather chest that's invis, but as far as I know still unable to be transmog'd, it'd be nice if it could be though, can come up with some awesome monk/rogue type pit fighter looks that way

I should check my little Tauren shaman. She's got some invisible boots. I didn't realize they were invisible until I was running around Thunder Bluff and thought that I'd somehow forgotten to add them to Outfitter or that I'd mistakenly vendored or de'd them.

They might be the tsunami boots, but I thought they were cloth or leather.

Fairly certain these leather boots are invisible on taurens/worgen!

(I'm necroing ERRYTHING today >.>)

anything that is a simple 'shoe' graphic, where it doesnt have a graphic going from ankle to knee cannot be seen on trolls, worgen, tauren, and draenei due to the lack of a) proper proportioned feed (trolls) or animal paws/hooves :3 cant say anything for any other invisible items but there are a rare few sets where the belt is the exact same model as the legs so you can overlap them with no trouble. I wish i could remember the one set in particular i noticed it in... it was mail, it was like the outrunner set except the belt was same graphic as the pants and it was a desaturated lavender color with black outline

There are quite a few boots that don't show on trolls, tauren, draenei and worgen. Most are cloth and leather.

Tsunami Boots are the only mail ones I know of, which you listed.

For plate there are three (or six if you count heroic versions) of boots that won't show. They aren't easy to get being from ICC and RS.
Ancient Skeletal Boots plus heroic version
Boots of the Funeral March plus heroic version
Foreshadow Steps plus heroic version

I'll post later with cloth and leather boots because it's late now.
