Yes, eventually a pawn in the enlistment camp tent named Jonathan(spellings wrong) will sell a pair of items (The Secret of Metamorphism) after you purchase them, you can alter appearance at main menu.
Be careful though, the one you can get part way through the game (the secret I believe) is a one time use only item. Even if you don't change anything, once you've exited the editor, that's it until post game. Then you can by the art, which you can use anytime you want.
