Please use this size chart to help you choose the best size for your mermaid tail. It is best NOT to size up because the fabric will stretch in the water. The stretchy nylon-spandex fabric allows plenty of room for growth.  I'm happy to customize the sizing if needed. Just order the closest size and send me measurements!
