Re: Avengers 2 News, Rumors, Etc. Pictures until release...
MCU has been pretty good about making the costumes pretty believable. The only one who wears something that is a costume in-universe is Cap. The leather and such that the SHIELD folk wear is borderline costumey, but well within tolerances. I'd rather they stuck with that pattern and only gave costumes to people who would reasonably go out of their way to make such a thing (or can be explained away by being from an alternate dimension).
