    Sweetheart Swimsuit

    This is the most comfortable costume I have ever had. The fit is very good. The style is wonderful and flattering. Has been worn in the sea several times now and is still looking good. I would definitely recommend deacon & blue to friends and family.

    Brilliant just brilliant!

    I love this swimsuit I’ve had soooo many over the years and always thought a Deakin & Blue was too much to pay for a swimsuit but it is so worth it. The most comfortable I’ve ever worn and brilliant for actual swimming too! Keeps everything covered and secure!

    Sweetheart swimsuit navy and plum munro

    I thought about buying this swimsuit for quite a long time due to the cost of it , however it is more than worth the money as it looks and feels absolutely fantastic, and the quality of the swimsuit is really good. I am sure it is going to last me a long time with lots of use. I have all readymade good use of it ,and have quite a few comments on how good it looks .

    Very flattering and extremely comfortable

    I spent quite a long time considering whether to buy a Deakin & Blue swimsuit as they're not the cheapest, but having just come back from a two week beach holiday I'm so glad I did. The cut is very flattering and even more importantly it's so comfortable. Straps are super-soft, don't dig in, and it's an absolute join to swim in. Everything stays put, but with free range of movement. Now I just wish I'd bought it sooner!
