Love the xover one piece
I have now purchased 3 x xover one-piece kozii's to have in rotation. They are fantastic, everyone comments on them at the pool as the colours are amazing and fit very complimentary. Tip size up by 2 sizes. Love these kozii's, of course I need a 4th pair now, ha ha

CT 2 TONE SANGRIA XOVER ONE PIECE

3rd kozii bathers
The mermaid xovef was my third Kozii bathers I have bought and is my favourite so far. The colour I find is lasting longer (possibly because I am taking care of it better). As a swim teacher I love how comfortable I am while wearing this one-piece, and how it feels secure and looks amazing.
