Last-Minute Fairly Odd Parents Halloween Costume

This is the first Halloween that my boyfriend and I spent together. A few days before the Halloween event, I was freaking out that we didn’t have a definite costume idea and I thought we would not end up with one. We went to Michael’s the night before of the event and my boyfriend was like, “What about Cosmo and Wanda?” I thought it was a very spontaneous and cute idea. We wanted to spend the least amount of money as possible since neither of us had a job. At the end of the night, it costed us $20.48 to make both outfits. We had to do some arts and crafts for some props, but that was basically it. Here’s our DIY on how to make Cosmo and Wanda!


  • – White dress shirt
  • – A black tie
  • – Black dress pants (or jeans, if you want to be casual)
  • – Green hairspray: $6.99, a local Halloween store (optional)
  • – Pre-made yellow crown: $2.99, Michael’s
  • – Wand: made by a wooden stick, gold foam paper cut into stars, tacky glue, and for an additional design, black pipe cleaners to decorate the stick.
  • – Black vans or dress pants


  • – Yellow t-shirt: 2/$5 ($2.99 each), Micheal’s. I cut mine into an off-the-shoulder but you can design the shirt however you’d like.
  • – Black pants, leggings, or shorts
  • – Pre-made pink crown: $2.99, Michael’s. I chose a pink crown to substitute for my lack of pink hair.
  • – Pink hairspray: $6.99, local Halloween store (optional)
  • – Black flats, Vans, or Converse
  • – Wand: designed just like Cosmo.

As for the wings, we found giant chenille pipe cleaners that was 6 ft long, so we made two loops for the each of us and pinned it on the back of our shirts with a safety pin.

Our last-minute fairly odd parents Halloween costume was a success. At the Halloween event, we were nominated for the costume contest and to our surprise, we won 2nd place and a $15 Red Mango gift card! So many people complimented our costumes and said it was very unique. I hope you enjoyed this quick, easy, and cheap version of Cosmo and Wanda. Have a happy Halloween!

      My friend and I are planning on doing the Cosmo and Wanda costume for halloween. We already have our shirts and supplies but I just had a quick question about the hair dye! My hair is black, and I see that in the picture your boyfriend looks like he has black hair too… Was it hard for the green to actually show? Or what product did you buy and from where? I’m really stressing about the dye because my hair is black and I only want it to stay in temporarily. Please contact back soon! Thanks

        Since you have dark hair you need to spray it with white first and then apply the color because the colors won’t show up on plain dark hair. Good Luck and I hope this helps :)
