I have a fairly large number of outfits I change between depending on the climate of where I'm RPng and the situation (commoner's clothes, disguises, Flames uniform, something more formal, etc). Most, though not all, are put together with All-Class gear so I can swap between an ACN book and a PGL weapon if I have to... Which makes nice-looking sets a bit of a pain to work with when they're for one class only or Disciples of War/Magic-locked.
