You can buy a large number of shirts from various vendors around the world. Most of them appear to be in the Wrath of the Lich King expansion.

Based out of WotLK’s Dalaran Karandonna sells 16 different shirts, ranging in price from the 25g Amber Filigreed Shirt to 1,000g for Embroidered Shirt.

Also in WotLK’s Dalaran Angelique Butler sells 2 shirts. Both have a medical look, unsurprising given Angelique is a first aid vendor.

Found wandering around Old Hillsbrad Foothills, Thomas Yance sells 19 different items for transmog, including 5 different shirts. Most of the items used to be given to starter characters and I believe this is the only way to obtain them now. To reach him, go to Dalaran and use the portal to the Caverns of Time. Once there, go into the Escape From Durnholde instance to explore Old Hillsbrad Foothills.

Finally we have Broxel Goldgrasp who sells souvenir shirts at the Argent Tournament at the northern edge of Icecrown. There are 5 shirts for each faction and their designs are based around the various capital cities. eg you have the Undercity Doublet and Stormwind Doublet.

There are a number of Cloth armor merchants around Azeroth who sell three shirts.
