This instructable will be on how to make a unicorn costume using a hoodie as the base.

I have always wanted to be a unicorn. They have magic horns! They have pretty manes! And historically, they are very dangerous! Therefore, I would be a unicorn for Halloween. So I was. I was a fantastic unicorn. And using this instructable, you can be a unicorn too! Yay!

Step 1: Planning.

Picture of Planning.


  • Thick, plain white sweatshirt. You can use a sweater but it would need to be thick. Buy this from a thrift store.
  • Plain white sweatpants. I ended up using leggings, you really use anything plain and white and pants. Also buy this from a thrift store.
  • Red, yellow, green, blue, and purple yarn. You can use orange if you really want to. My local craft store didn't have a good shade. I used Lily Sugar n' Cream yarn, it was thin enough, cheap enough, and cotton.
  • Silver/white glitter felt. You really don't need a lot, I bought a tiny 9x12 sheet.
  • Plain white felt. Again, you don't need a ton, I used a 9x12 sheet.
  • Bright pink felt. This you need more of, the tiny pink sheets won't cut it unless you are making this for a small child. To tell the truth, I don't remember the exact dimensions of the fabric I used, I ordered a lot more than I needed. It was around 15x20 inches. This is what I bought, in shocking pink.
  • Green felt. You don't need a lot of this, while I already had some in stock, I would suggest using a 9x12 sheet.
  • Silver embroidery thread. I already had some in stock, but it was just like this.
  • Pink thread to match the felt. Something like this.
  • Small amounts of stuffing. Find this one yourself, I'm tired of searching for links.


  • Hot glue gun & glue sticks
  • Regular needle and embroidery needle. Basically, a basic needle and a thick needle. I guess you could use an awl instead of the thick needle, but I don't own one and have no clue how I would use it.
  • Regular and fabric scissors
  • Pins
  • Cardboard
  • Parchment paper
  • Regular paper
  • Tape
