The Mermaid Kat Shop is for all real life mermaids, mermen and mermaid lovers. You will find different kinds of mermaid tails for children, men and women. We offer fabric mermaid tails or tails made out of high quality silicone.

Before Mermaid Kat opened the Mermaid Kat Shop she had many years of experience and training in differed fields.  She worked as a fashion model, scuba and freediving instructor, underwater model, professional mermaid and mermaid trainer. For Kat it was important to create high quality tails that are strong enough for proper swimming. With the combination of all her skills she and her team created mermaid fins that look as realistic as possible but are also high functional and safe to use in the water.
