If the zipper is fake, it can be made smaller and thus more 'in-scale'. The realism of a lot of 1/6 scale zippers is dampened by the fact that, in order to be functional, many of them have to be made over-sized.
There are some exceptions, of course, but oversized zippers *is* something that can be problem with a lot of 1/6 scale clothing.
