If you are part of a group of parents (such as a Mom’s group, club, etc), you could organize a Halloween costume swap. Have everyone bring last year’s costumes to the swap and they can exchange them for costumes that will fit their children this year. Make sure that you require the costumes to be clean and in good condition. Nobody wants to bring a nice costume and be stuck with a dirty, ripped costume.
