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.
