I remember a Stan Lee quote in which he said that movies and comics are two totally different mediums, what works in comics wouldn't work in live action.
For me I don't mind small changes but only to accommodate the movie.

As long as the superhero wears the outfit whether its the actual costume or a new costume with the old fashioned colors from the original costume its fine too as long the costume doesn't look god awful or whatever.
I happened to like the 1990 Captain America too, I'm not a fan so I didn't mind the liberties taken with it.
