Halloween is for everyone, but this year, the cutest costume awards go to Witney Carson and more celebrities' children. Carson kicked off the holiday by attending Disney+ Halloween Fest on Saturday, October 25, with her husband, Carson McAllister, and their two sons, Leo, 4, and Jet, 2. The family dressed up as characters from Peter Pan, with Carson channeling Tinkerbell. Her husband was Peter Pan, while their boys dressed as Captain Hook and Smee, transporting fans to Neverland in an instant.
