Mermaids are one of the most-loved of the mythical creatures, especially by little girls. These beautiful creatures have been featured in many stories and movies throughout the past few decades and they represent the mystery that lies beneath the waves. We have a wonderful collection of mermaid costumes, any of which are sure to dazzle your child and ensure that she is able to dress up as something she loves. Our mermaid costumes come in a wide variety of styles and sizes so there is sure to be something that is perfect for your little girl. All of our mermaid costumes come with a dress and our Magical Mermaid costume also includes a headpiece and arm bands. There are also many accessories that are sure to add an air of authenticity to your child's mermaid costume, including shoes, jewelry, makeup, a crown, a staff, a wig, and even a seashell. Once your child is in full costume she will be transformed into the lovely creature of the sea and she will go gracefully (or not) to each and every house trick-or-treating and feeling proud in her beautiful costume. You will definitely not want to miss out on the photo opportunity this Halloween will be.
