Bring your fantasy to life with our Sea Monster mermaid tail and monofin set. Have you always dreamt of being a mermaid, but maybe not the good kind that's always portrayed in movies? In some cases, there's fun to be found in being bad and some of us have always itched to play an evil villain. If you can't get a role in the next blockbuster, put on our Sea Monster mermaid tail and monofin set instead and rule your kingdom the way you want, with flair and darkness.

The best part about our Sea Monster mermaid tail and monofin set is that it not only looks great on land, but it looks wonderful in the water too. Learn to swim in your pool with it or take it to the ocean once you've mastered swimming with a fin. Our mermaid tails and monofin sets are designed to withstand the sun and water, so you can have aquatic fun.

Monofin included


Sea Monster is an awesome mermaid tail design inspired by fantasy beasts with reptilian scales. Made with a compelling combination of blacks, yellows, browns, and greens, this tail looks great with a black monofin.

Comfort and Quality

Our realistic scale mermaid tails are made from 80% polyester, 20% Elastane (spandex) material with 4 way stretch. The swimsuit material is very comfortable and works well for swimming, or as a mermaid costume.  

The scales feature a 3-D design in swirling and textured hues. The fins are designed to look like a real mermaid tail.
