So as an adult, I still secretly want to have a mermaid tail and at swim around a beautiful lagoon. I found an Etsy seller creating swimmable tails that let you believe you are mermaid with glittering tails and fins.
Earth Song Designs has adorable mermaid tails made of swimmable fabric and a custom made monofin fluke that help you swim through the water.
