    Happy Shopper :-)

    Fantastic cosy, sizing and quality were wonderful. The underwire bra was comfortable but left you feeling secure. Great adjustable straps and good bum coverage. Felt lovely to wear and made me feel happy.

    Great bathers

    Great quality and coverage. It’s able to hold the girls in, but the straps have come undone a couple times

    Beautiful cossie!

    Great fit, true to size & colours & pattern are beautiful. Only one small problem, the straps detach from the back when I put it on.

    Would buy again

    Love this. Looks great on, only thing is that it sits lower than I used to but not a big deal just need to get used to it. Great service, fast delivery.

    Island nights swimsuit

    Your service was without fault. The swimsuit appears to be good quality, and fits nicely. I love the black background and the colours of the pattern and I’m looking forward to wearing it at the beach. Thank you
