The problem is not maid uniforms per se, just the cheapness of some of the outfits. If they would spend 3x more and get something nice from a company like candyfruit or a custom outfit, the movie would be many times better. Look at the more complicated dresses in vintage movies like DRM-004 with Mai Haruna, or the one English Maid dress Penny Flame did when she shot in Japan. Great stuff.
