Trying to top last year’s costume is always a challenge. Fortunately, kids often have costumes lying around the house from playing dress-up. If you can persuade your kids to not get a new costume this year, try changing up an old one by mixing and matching parts from costumes of years past or adding accessories to create a new character. If that tactic doesn’t work, check out this year’s most popular Halloween children’s costumes. Just make sure to shop early so you aren’t “Frozen” out by short supply.
