It's a local Denver store, but they ship. Not sure if they do international.
See if your local community or college theater (if you have one) rents out costumes. Ours does during October!
Not exactly what you asked, but have you checked local thrift stores?
I haven't yet, but yes thrifting will definitely be on the menu! Right now I'm trying to think through how I'm going to craft a couple of the pieces I aim to make and was hoping to find some costume specific sites to draw inspo from (and to start browsing for a wig and accessories.) There's just so many niche webstores selling junk product that my eyes were starting to cross.
