Cap?

Would anyone local have a plain baseball cap with no writing or logos on it that I could borrow for a show I'm in this weekend? It could be any color except pink (which is the only color BB cap I do have). Alternately, some other kind of cap that a little boy of the 1930s or 1940s would wear (beanie, porkpie, etc), as that is the character I play. I so very much don't want to schlep down to Garment District. Thank you anyone who can help!
