So - what’s the matter? Why not go straight for a original uniform (jumpsuit) at all?
Imho it’s totally suitable for a “girlbuster” (um… well - maybe “fembuster” … meh - that may sound weird too, but anyways…) as well, i never really understood the need of an explicit female-version of the original ghostbuster-uniform at all, well - at least as one’s not especially on the quest for some “tempting-sexy-girlish” outfit (which may be neat, but still may bring a bit of sillyness to the “seriousness of busting-business” with it ) of course.
I have two women in my group. One is 5’4" and the other is 4’10", both wear the standard 27-p flightsuit in khaki. Just get one in her size, you should be good to go.
