    The envy of the Swim Group!

    Initially I purchased this costume in my usual size 8 as I hadn’t read the sizing guide; it was tight squeeze to get on. However, once on it looked amazing and as stated, the costume stretches to fit over a couple of wears. But, because I loved it and to be genuinely sure I had the correct size I purchased size 10. Probable a better fit, but I still wear both as I know I fluctuate in size. The material is robust and feels great for sea swimming. Plenty of comments I on how great it looks too.

    This has to be the most stylish and flattering swimsuit I have ever owned. It's stunning. Also very comfortable. Great customer service too.

    Flattering and comfortable

    Great swimsuit - really flattering and comfortable, and the mesh bits have sun protection. I actually disagree with the advice to size up - I tend to be a 14 and the 16 was far too large for me. Even the 14 is a little roomy in the bottom area - especially once wet - so I think it does depend on your body type. I think I could probably get away with a 12.

    Best swimsuit I’ve ever owned

    I honestly can’t rave about this swimsuit enough! I swim in it about three times a week and it is perfect for doing actual hard exercise in, for the first time in years in confident my boobs are going to stay in place! Normally the trade off for such confidence is a boring, unattractive suit but this is so gorgeous! The mesh is super flattering and sexy and the shape of the straps on the back is really cute too!
