I'm a fashion designer and horror enthusiast, this project sounds like it would be right up my alley.
I do not live in the USA, but I can still work with you online by sending a full design and guiding you through the process of making the garments (choosing materials , construction, taking the designs to a seamstress, post production, etc), as I have done several times before.
if you choose to contact me I can show you examples of my work and discuss exactly what you expect of me so I can adjust my bid accordingly
I would love to hear more about your project, aesthetics and references (even if you don't hire me, honestly, it sounds like an interesting project)
regards,
Laura
