With a large group of friends, this costume idea would work well. All one needs are rainbow shirts and then either white paint or an iron-on a sticker. Most people have a colored shirt lying around in their house somewhere, but if they don’t, places like Walmart or Michaels sell them for $8 or less. After getting a shirt, iron on the “M” from M&Ms or a hydro flask icon, which can be found online and may vary depending on what you choose to do. Adding any accessories to each piece is optional. If one doesn’t add any, tracing an outline on the shirt before painting with white paint costs $3 but will complete the look. – Tiffany Li
