This Mary Poppins costume is supercalifragilisticexpialidocious (which, if you remember, means wonderful). Another beloved childhood character is Mary Poppins, and like the other characters we’ve seen on the list, she has a few trademarks that are easy to recognize, from her clothes to her magical briefcase and most importantly, her umbrella.
Since the Disney classic was released in the sixties, Mary Poppins has become a household name in the U.S. and around the world. The musical film, which was later adapted to the theater, remains one of Disney’s most popular and beloved films to this day. Yet, for some reason, it’s not often that we see a Mary Poppins Halloween costume, let alone a costume this authentic.
