One thing I discovered when looking for pictures for Dartz' crew of 33-S sexaroids: from the side angle, it sure looks like they're all the same height. Like, that makes sense, right? You'd have a standard design that you'd extend with various, uh, add-ons. I'm not sure where Dartz got his figure of 170cm for Meg, but that seems fine. Sylvie is similiar in height to Priss, but I never see a scene where one of the two isn't in the foreground.
