Amanda searched the store, until she found a Mermaid outfit. Being 24 and a having a mix between a mermaid fetish and fantasy after growing up watching movies like "Splash", "The Little Mermaid" amongst some of the mermaid stuff she's seen. Amanda noticed the tail and top looks very professional as the scaling felt so real and fishy. She quickly bought it and the old woman over the counter hoped she'd like it.
With that Amanda was off to try it out. She went to the beach and checked getting the costume off her list. Upon opening the package she noticed how long the tail was. "Well, a mermaid doesn't have a belly button" Amanda said. She took off her clothes to try it out. Doing this revealed her beautiful womanly body. She had a very well built brest long legs and hips that kept her fending off men. She put the costume top on first and was surprised at how well it fit her. She then put the tail on at the bottom of her feet, and started to pull up. Suddenly there was a tingle in her legs as if they were becoming one limb.
As Amanda zipped the tail she felt something was wrong. Her hair felt longer and thicker than before, her legs started to go numb, and as she fell face forward into the water Amanda felt several internal organs shifting. As Amanda began to swim it was evident it wasn't a costume anymore. Especially since she felt water in her gills
