Ballet Birthday Invitations Friends Birthday Party, Themed Tea Party: Any Ideas For Doll Or Ballerina Costumes?

Friends birthday party, themed tea party: Any ideas for doll or ballerina costumes? - ballet birthday invitations

I'm going to a birthday party for my friends, and over their tea. it must go like dolls and my idea is a dancer, seen in jewelry boxes? Other suggestions for dolls, make-up and costumes welcome. I have only black ballerina, so if I'm working as a dancer, the costume is black.
Thank you.
