Lady Ranicorn

Lady Rainicorn is a secondary character in the show Adventure Time. She is a unicorn rainbow hybrid, and she is the love interest of Jake the Dog. She only speaks Korean in the show, in a cute, high pitched voice. (I thought it was Japanese, but the all-powerful internet says otherwise.)

The inspiration piece for the costume is a rainbow maxi skirt. The long lines and high waist match her long rainbow body. The colors aren't exactly the same, as the skirt has no pink, but I'll probably leave the white portions white.

Lady Rainicorn from Adventure time

My main project for the costume will be a unicorn horn. There are many videos online on making a unicorn horn with polymer clays, but I plan to use instamorph, which I think will be lighter. Instamorph is a product we used in an instructables session, similar to "friendly plastic." It consists of plastic beads that you heat in water. Once heated, it takes on a silly-putty consistency. When it cools, it hardens into plastic. You can also re-heat and remold it. I bought a sizable jar of the stuff after the instructable night, but this will be my first project with it.
