Do you have dreams of an endless ocean? Exploring the depths of the sea and discovering all sorts of mysterious creatures and treasure that has fallen to the grottos? Perhaps you've imagined magical transformations or might have even seen a sultry-looking creature while out sailing. Well, don't worry. You don't just have water on the brain. You might have fallen under the siren song of the magical merfolk. We're here to make sure that your transition from land legs to sea flippers goes well. With our Mermaid costumes, you'll be part of their world in no time. All you need to decide is what kind of mermaid you want to be!

Some of the earliest stories of merfolk are connected to the legends of the sirens. These mythical beings lured sailors with their beauty and their magical songs. Sure, some of them made quick snacks of the humans when they were dashed on the rocks. But, others would fall in love with humanity and bestow them with the ability to breathe underwater. Still more became entranced by the world of the land-lovers and dreamed of having legs of their own so they could explore a land touched by the sky! 

You'll be able to bring all of these stories to life when you try our Merfolk costumes. Naturally, you might be most interested in some of the famous merfolk out there. Of course, we have to start with the Little Mermaid, herself. If you'd enjoy a costume that leaps right out of the Hans Christian Andersen story, you need to look no further than our red-haired and green-finned Little Mermaid costumes. The mermaid cut skirts will give you the look of swaying hips and flipping fins while still letting you break out in song and dance with your legs. (No need for strange sea witches!) 

You can also rule the seas by becoming the chief of all merfolk, the god of the ocean, Poseidon. You might wonder how this aquatic deity keeps his beard looking so great despite all of the saltwater. Well, we have to assume that's part of his ultimate power! Of course, the greatest part of a Poseidon costume is how great you'll look next to the queen of the seas, the Siren. There aren't many couples' costumes that are better than this. A duo that rules the waves together stays together, right!? 

Don't feel like you have to be the most iconic of mermaids, though. We have several Mermaid accessories and mermaid wigs that will help you create your very own character. Choose from some of our fish scale leggings and seashell tops to combine the colors and style that shows off your corner of the ocean. Look at all of this mermaid stuff. (Isn't it neat!?) If you're looking to make your mermaid collection complete, you can pick up a trident and magical conch shell, too. Before long, you'll have an entire school of mermaids. (We're not sure what the word is for a group of mermaids, but we're certain that it is a whole ocean of fun!)
