The wardrobe has released and players are buying shirts up like crazy due to needed 15 for an achievement which leads to “the Fabulous” title! But don’t think players are stopping just at 15, many are buying all of them just to get one shirt closer to knowing all the visuals!
Here is the TSM group for all the crafted shirts for you to import.
Some of these shirts are learned from the trainer while others are dropped / bought from around the world.
Use this Wowhead link to figure out the locations on how to obtain the ones not trained.
I personally keep two of each shirt on the auction house currently. Later down the road when sales start to slow down, I’ll probably only make one. Keep in mind you will need to setup crafting and auctioning operations for this group as every server is different.
