Costume jewelry (Brooklyn)

I'm looking for some old costume jewelry earrings chains stuff like that I do a project at my church called post-apocalypse cyberpunk GI Joe and Barbie so I use the costume jewelry instead of the real jewelry to make it more realistic with earrings and chains around the hands and chains around the legs all kinds of stuff so I make it really realistic so if anybody has any please tell me I would appreciate it I teach the people at my church all this stuff and they like it because they said it looks so real like it looks like a realistic person
