Melanie Drygalla

The shop is amazing! Costumer service is just beyond anything I've ever expierenced. I ordered a silicone tail for my underwater wedding and like every bride I wanted it to be perfect. It was beyond that! The colours, the fin, the feeling during diving - it was just so perfect. The moment I put it on and the second moment I took it to the water for testing I knew I bought quality. Smooth and comfortable. As a diver I know the critera of monofins, and they just feel like I slip into my diving fins. I also bought a simple monofin for training and its the perfect fusion for freediving and mermaiding, but you know instantly those are made by professionals who really know their stuff.

Nina Rief

Kat is so kind and professional, I cannot recommend her courses highly enough!
Being a mermaid has always been a dream, and I feel her teachings provide a safe and fun foundation to any aspiring performer or hobbyist. The tails are just gorgeous, and the team truly make any vision come true to create your dream tail! I love my glittery mint magic silicone fluke 💖💖💖

Jenia Sanders

My silicone tail is a golden peice of art! Great quality and simply gorgeous. The customer service is great as well. So kind and professional.

Emma Olsson

I got my first silicone tail from Mermaid Kat Shop. The quality is excellent and the size (made exactly to my measurements) fits perfectly! I'm very happy with my beautiful rainbow tail! I also own a fabric tail from them, and I love the vibrant colour so much and the matching bikini is my favourite :)

Dora Varga

A wonderful shop experience. The shop itself is decorated with a love for detail. The products are of great quality. The team is lovely and will do everything for the client to be happy. It truly did so for me.
