Evidently zombie maids are a big thing with the lunch crowd in Japan. I am not sure what the exact trope is-perhaps you just want to dress up in a sexy maids costume, but you want to throw in a little Halloween too-with the zombies. I like it.

The sexy maid outfit is simple, affordable and easy. I think this is cute. Or I think this is the exact one.

The makeup (the scars) appears to be custom. I’d start here for a scar kit that fits your size.
