    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.

    Long sleeve swimsuit black monroe

    I love this swimsuit. The bust support is superb and the mesh sleeves are so much better to swim in for sun protection than a rash vest. Have had many compliments it is so flattering. And the fabric has a really pleasant soft handle to it once you’ve wriggled in.
