Haven't you found any armour yet? The initial appearance should be covered once you get a breastplate and leggings, etc.
If you've looted everywhere in town, keep an eye out when exploring, and check with George periodically. NPCs restock every 10 or 15 minutes real time, depending on the NPC, though can hang on to things that you sell them, which stay at the top of their inventory list.
It is possible to switch to the appearance to one of the other player characters, though.
Some more hex offsets...and maybe check out
Teleporting Anywhere, via hex editor as a reference
