They come in pretty much every color and style (sparkles! rainbow!), even smaller horns for tweens like mine who would probably wear them as a regular accessory. Just be sure to email first to make sure you'll get it in time for Saturday. And hey, if not, they make a very cool holiday gift, or a "just because you feel like being a unicorn today" gift. I like that idea too. Purchase the handmade unicorn horn headbands from BrooklynOwl.com. Shipping is 1-3 days but make sure to check before you order.
