Dress up play clothes (2nd Avenue Royersford)

Hello! I am the new children’s librarian at the Royersford Free Library. I am trying to assemble a dress-up corner for imaginative play. Either old Halloween costumes and such, or even grownup clothes that would be fun for fancy dress up (like interesting hats, gloves, costume jewelry, etc..)

I’ll be going to thrift stores as well, but if there is anything I can acquire without using the library’s tiny budget, that would be even better!

Thanks in advance!
