    My new favourite swimsuit

    I’m absolutely delighted with this swimsuit. It’s the perfect fit, very flattering and so comfortable. Wish I’d found Deakin and Blue sooner!!!

    The Best swimming costume ever

    This is my second swimming costume and I alternate the sleeveless Monroe with this long sleeved version, every day when I swim in the river. It gives me support across the tummy and bust line and I feel confident . It really is a game changer

    Chic and stylish swimsuit

    Elegant looking swimsuit. Needs a bit of a wriggle to get in and out of, but looks lovely on. Would have given 5 stars if it had slightly more coverage in the groin area. My previous swimsuits all had boy short type legs and I do find myself tugging the bottom bit down before I get out of the water. Would certainly consider wearing this as an elegant wrinkle free top with shorts or trousers.

    The swimwear revolution

    At Deakin and Blue we're reinventing swimwear: developing pieces that are transformational in how they feel, how they move and how they are made.

    FEEL BETTER

    Sarah’s body story

    "I am so aware of what my body gives me – this ability to scuba dive, free dive and swim. I don't even consider what it looks like when I'm doing those things. I don't care what size my body is. I mean, not only has it given me the ability to do the thing that is now my job and my passion, it’s also gone through pregnancy and a terrible birth and come out the other side and now I have a beautiful son. So, yeah, my body is incredible for what it can do."

    1. Soft, supportive double-lined fabric

    2. Smart panelling for a sculpted shape

    3. Extra-long back zip for easy changing

    4. Buttersoft UV-protective powermesh sleeves & hips

    Do better
