Here is my White Hunter Transmog Gear that I was using a long time ago in WoW.
The list of items:
Helmet: Steelspine Faceguard.
Shoulders: Ancient Pauldrons of the Monkey.
Chest: Ancient Chest of the Wolf.
Gloves: Ancient Gauntlets of the Gorilla.
Belt: Fenclaw Waistband of the Bear.
Pants: Knight’s Legguards of the Boar.
Boots: Ancient Greaves of the Monkey.
Bow: Prideful Gladiator’s Longbow.
Tabard: Tabard of the Argent Crusade.
Besides the helmet and the bow, all other items are green.
You can find them in auction house, just search for “ancient”.
However, these green items have pretty low drop rate and it might take a while until you get your hands on all.
As you can see, the pants and the belt are not from the “Ancient” set, but they look almost the same.
If you have the other items, shoulders, gloves, pants etc, just browse the AH for pants and belt.
If your realm is at least medium populated, you will find something that fits.
For more information about the items, look for them on the wowhead website.
Many years ago, I was collecting all kind of transmog sets, based on colors.
This is how I got a White Hunter transmog gear, red, blue, black / dark etc.
Look for them using the search function.
