Sea All She Can Sea!

The ocean is a beautiful place to discover when your horse wears this mermaid princess costume. From the sparkling surface to the strange deep. It’s full of mystery. Who wouldn’t want to dive in and explore? Do you want to swim along with the dolphins, splashing to the surface in the sunshine? or maybe go down and explore the ocean floor. You can swim through the colorful corals, catching and releasing tiny seahorses. All sorts of treasures might be hidden in the sunken ship. Who knows maybe you’ll resurface with a strand of pearls, an ancient sword, a bejeweled crown? Straight out of a fairy tale illustration, the mermaid scale fabric is a bright rainbow of color.  You also get a gold crown adorned with pearls. Maybe finish it off with a seaweed boa!

You’ll love the comfortable fit your horse will have. So comfortable you can ride in it!

Easy on/Easy off

In general, most horses tolerate things pulled over their heads.  Therefore, putting on your horse’s Halloween costume is easy to do. Open the noseband Velcro.  Bunch up the slinky and slip it over your horse’s head.  Adjust the holes until your horse’s eyes and ears are in the center.   Slide the remaining slinky over the neck and shoulders. Close the girth attachment. Close the noseband Velcro. Your horse sleazy costume should fit smooth, like swimwear, but not tight.  Finally, attach the gold crown with the attached color-coordinated ties.


Your Mermaid Princess horse costume contains 80% nylon/ 20% spandex fabric. Therefore, it is machine washable and air dries fast. Additionally, follow our simple Care Instructions for best results.
