Yes, to our modern eye, contrasting gores can be pretty! And sometimes in the SCA you just have to work with what you have and that might mean you are forced to make some choices that would not be historical in nature if you do not have the right fabric or enough of the right fabric. "I only had so much fabric" is a very valid reason for doing something while "If I lived back then I would have done it this way" is really not unless you can show it was done (in other words, do not try to force history to conform to your own ideas on how things should have been).
