She is wearing a matching necklace and belt! Her hair is the same as her clothing - actually part of a scarf I bought in Primark in the sale (it was only a couple of pounds)
Here's a close up of the tail, you can see the netting under the Matte Accents.
There are some random droplets of Glossy Accents over the background and into some of which I dropped blue sequins.
I attached her arms to her body with brads, and they are still moveable - well, she'll need to stretch her arms and have a swim now and again!
