Gather a group of friends — the more the merrier — and have everyone choose their favorite candy color. Purchase white gloves, solid-colored tutus and suspenders and striped knee-high socks (available at party stores). Either buy or reuse solid-colored T-shirts to match the color of your M&Ms and white shorts to wear under your tutus. Cut out this free printable letter “m,” trace on white felt (available at craft stores) and adhere to your T-shirt with hot glue.
Now here's a costume that really pops (sorry, had to). If you can't find a red and white striped skirt, you can definitely hack one with some white tape or fabric paint. Get the instructions here. - Delish.com
