## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value and functional!
            
*by M***N on February 9, 2018*

I am 25 years old, 5'8'', 115lbs, 33-24-34, and I bought the largest size possible and it fit really well! Wasn't too short on me. It is swimable, I swam around in it without issue. My shoe size is 8.5 and I was able to fit in the monofin.The bikini top is meant for a kid, but if you seam rip it and move the "shells" around, you may be able to wear it? I did that but I wasn't comfortable wearing it, too revealing (and I'm just a B cup lol). I'd suggest just buying a different shell bikini top off of amazon, there are lots of affordable options.To put it on:Put the monofin into the tail. The end of the tail velcros, so slip the monofin in that way, then close it up.Gather the leg part of the tail down to the base (like putting on a stocking) then slip your feet into the monofin and pull the tail up.This tail is obviously not meant for walking, I'm surprised some reviews even mention it LOL.
  

### ⭐⭐⭐⭐⭐ I have blended into my new environment
            
*by D***N on August 2, 2018*

Day 20:The Mermaids have not suspected a thing the tail is similar to the other mermaids' and now they have friended me. I threw the top away and found better shells to help me blend into the ocean. Often though, I find myself adjusting the velcro on the bottom to hide my feet. The monofin is strong enough to play with. The Mermaids have begun to talk to me. I find this a perfect tail if you want to be accepted in the Mermaid society.
  

### ⭐⭐⭐⭐⭐ Happiest little mermaid in the world!
            
*by C***I on September 4, 2018*

When the product came I admit I was worried it wasn't going to fit.  But it is VERY stretchy.  I have not noticed any damage to the suit yet and she has worn it a couple times in the pool and she is not a careful individual.  She is very spontaneous and in the moment.  She has been wanting this for a long time but I wasn't willing to spend big bucks on it.  This was a great price for a great item.  The top did not fit as was in the description.  She couldn't care less.  I also feel as does she that it needs more velcro at the bottom on the fin area.  We are going to get some so we have it ready for next year.  Her mother also tried it on and she is about 5'4 and weighs about 130.  My granddaughter is a little chunkier and it still fit just fine.  It is the largest size as I wanted something that she would be able to wear next year too.  I would say buy it with confidence!  We love it!
