    Essential Swimsuit

    I thought about buying a Deakin and Blue swimsuit for sometime, frequently revisiting the pages. I finally decided to buy one and picked the Essential in black in style Munro. I used the measuring guide to select both the style and size. I was a little reluctant as the measuring guide put me a size up from where I expected to be (I am an apple shape). However I believed in the guide and went for it. The size turned out to be perfect. The material is much thicker than other swimsuits that I've bought, but I think that's OK. I'm looking forward to lots of use.

    Brilliant swimsuit

    The fit of this is superb and true to size. It’s thicker than many swimsuits but feels fabulous in the water and clearly looks nice enough to attract compliments! Money well spent.

    At last a swimming costume that fits!

    Delighted with my new swimming costume. It actually fits and has given me the confidence to get back out there and enjoy the water.

    Great swimsuit

    Loving my new swimsuit but unfortunately after buying it I have discovered I have breast cancer and will have to have a mastectomy - do you or would you consider doing mastectomy swimwear?
