Where can you buy waterproof mermaid tails for under 50 dollars?

Not many places sell tails for that cheap. unless you rent one or better chance is to make one.

The instructions are simple to follow so ask that question and we'll give you tips.

.1. cut any coloured rubber into hundreds of little triangles.

.2. Stick them all over the tail like scales, the point of the shape should be facing down(all of them) stick it on with any glue.

.3.maybe sprinkle some some glitter all over the tail if you want.
