    X back sizing

    I found the swimsuit did not have enough fabric to contain the ‘side boob’, though it was the right measurement For my bust size. The straps scrumpled on the shoulders rather than remaining flat. Otherwise I liked the fabric and loved the colour and ethos of the company.

    A revelation!

    I’ve never spent so much on a swimming costume and was a little dubious of the hype, but it’s true - this X-back is the most comfortable I’ve ever worn - and supportive of my big bust. Worth every penny.

    Love this swimsuit

    The blue swimsuit is lovely and comfy. For a change the colour is just as it looks on the advert. It fits well and I feel secure and comfortable in it. When I have the spare funds I will buy another in a different colour as I swim a lot. The packaging it arrived in was lovely too.
