I ordered this in xs and it was too big. Returned it and bought the largest child size that fits perfectly. They were great about the return and refunded my money as soon as it was shipped. Great company to buy from.

It's definitely a cheep option for a tail, but it's seriously a great tail and my last one lasted me maybe two years. Note though that of you wear this in pools more often, there will be holes after a while because of the pools rough cement.

We bought our first FunFin in March 2022 in child's large/extra large for my 11 year old ($50). It fit her perfectly and fit matters because you want the plastic monofin, which was included, to stay on snugly, but be able to be "popped off" when needed. She loved it for imaginative play and games with her siblings in the pool. Her sister, who is 13, wanted to join in the fun, but we had to move up to adult sizes for her, which meant a higher price. So we paid $90 for hers, which is actually just one size up, based on the measurements included in the listing. Oh well!

The listing was accurate with the measurements and I recommend using them to help you decide on which size to purchase.

I read a few reviews about pilling and tearing at the tail, but we haven't experienced any tears, and if there are pills (tiny balls on the material as it starts to break down a bit), we don't notice or care.

I wouldn't recommend purchasing the mermaid tail without the monofin if you hope to swim with it. Otherwise, all you've really done is restrict movement in the water, and end up with a floppy, material tail when you are out of the water.

I expect to only get one swim season out of them, as the girls are likely to have outgrown the sizes by next year, but Texas summers last 4 - 5 months easy, so that's a doable investment!

My niece loved swimming with " a real mermaid " worked in a pool

We have many FinFun products and mermaid tails. I bought the first when my daughter was about 9 or 10. I reserched all the mermaid tail options and found that at the time there were a lot of warnings about children drowning or almost drowning due to mermaid tails. The problem being that the tail would have an air bubble causing the child to go end up face down in the water and they couldn't flip over. But FinFun tails do not have that problem because the material the tail is made of does not trap air. So my daughter used it for about 3 years and shared with all her friends so it got a lot of use before it finally got a few holes in it. So I have bought two more so my 1st daughter can have a larger size and my second daughter can have one of her own. And now I have bought this one for my niece because she loves my daughters tails too. I even use the monofin myself because it is so much fun to zoom through the water like a real mermaid.
