Q:
Changing the clothing shown on screen
Sadly no. You can’t display town clothes in combat. This is something I and many others asked for repeatedly during the betas, and yet was never implemented, nor did we ever receive any explanation as to why it is the way it is.
In any case, there are a few sets of town clothes available in the gem store. I don’t recommend wasting either gold or dollars obtaining them though.
Town clothes primarily come from the gem store. You can wear them even when not in town by going to your hero page (default key H) and then clicking on the top hat and cane icon at the top of the page to toggle on your town clothes. This won’t affect your armor but the first time you get into combat while wearing your town clothes you will immediately shift into your combat armor. If that happens, you’ll have to toggle town clothes back on again after combat.
