How does Transmog work cross-realm?

Heya peoples,

I've been farming the Grievous Gladiator's Ringmail using an alt on another realm to try and get the transmog on my hunter. (This is a mail Shaman item and my main is Hunter) Everywhere I checked on the forums it says it should work out this way. Now I've had the item in my inventory for a full day and I still cannot find this item in my transmog-page on my hunter.
Now is my question, Do I have to wait even longer in order for it to load to the page of my hunter, or did I do something wrong?

I hope you can help me out!
It is Shaman gear so it won't be available to transmog as a Hunter sadly. The helm, however, can be transmogged because there is a non-Shaman one that drops from Ordos (Olivia's Graceful Gaze). Also if you buy the set with 12 Marks of Honor on a Shaman it unlocks the helm for Hunters (which is what I did).

I can verify on September 2nd, 2018 that this still works.

Alliance Shaman, bought Grievous Gladiator's Ringmail Armor from Ethan Natice <Grievous Gladiator> in the Valley of Four Winds. This was the Season 14 SET (purple color), purchased for 12 Marks of Honor.

At first, the helm didn't show up for transmog on my hunter, but transmogging the helm to my shaman fixed this.

I understand, the thing is; I did exactly that. Bought in on my shaman for 12 Tokens and transmogged it on my Shaman. But it hasn’t popped up as a transmogable on my hunter. Thats why Im confused

[EDIT]
And I also equipped it on my shaman. It said in the chat that I unlocked the look for it.
