After many years of waiting, we finally got the classic "yellow & blue" costumes with the prequel, and I think most of us would agree that they did a pretty decent job with it, so since this new trilogy start in the 60's, they still have a long journey to end with the black leather uniforms from the original trilogy.
Taking into account that the sequel will probably be set some years later than First Class, would you like to see a new version of the x-men uniform?
and if so, what kind of changes would you like?
