This rainbow unicorn tail is perfect for a unicorn, horse, or pony costume; it is straight. It easily attaches to a belt buckle. You can also stick it inside the back of your pants or underneath a belt. It can also be attached by stringing it on a belt as well. It measures about 16"-23" The rainbow tail in the pic has already been sold, but I will make you a new one in the same style as shown. The final picture shows how to wear the tail; the other 2 tails are not included in this listing.
