If you're looking for a quick and easy costume that allows you some freedom in your style then unicorns are the way to go. This one has a silver rhinestone horn with small beaded accents in the front and white feathers throughout the crest.
It is held in place with three adjustable elastic straps. The headdresses are unisex and it doesn't matter whether you have hair or not, it doesn't affect the ability to wear the headdress. You can also wear it comfortably over a wig.
