A Mary Poppins costume comes down to a few neat pieces: a long dark or blue skirt, a white high-neck blouse with a red bow at the collar, a flower-trimmed boater or bowler hat, white gloves and a carpet bag with a parrot-handle umbrella. Get those and you have a look that reads instantly at World Book Day, a themed party or Halloween.
