Rainbow Unicorn Costume

The unicorn is a magical creature that symbolizes purity and grace, making it the perfect choice for a rainbow-themed costume. To create a stunning rainbow unicorn costume, start with a white base - this could be a onesie, a leotard, or even a dress. Then, add vibrant rainbow stripes using fabric paint or colored duct tape. Don't forget the horn! You can make a colorful horn using cardstock or foam, and attach it to a headband or a hair clip.
