alright so this question is really odd...
my friend is hosting a costume party, and she wants to go full-out geek.
she's already got a bunch of little cool details (maybe some pictures when she wears it? :]) but she wants a retainer.

i am wondering...how would i make a retainer?

she said she doesn't mind if i take molds or whatever, she thinks its fun.
i was thinking buying materials like a real retainer but A) i don't know where to buy acrylic and B) i don't know which kind of wire to use
so, any help?
thanks you!
