    So disappointed

    I’ve read so much about the brand and was excited to order. I was so disappointed with what arrived. I’m prepared to accept I may have ordered the wrong size? But followed the size guidelines. The cups were too small and the body was too long. The feel of the fabric was harsh. Maybe just not for my shape ?

    Lovely swimsuit

    Flattering fit. Comfortable and stays in place when moving about

    Monroe plunge back

    Really comfortable, no tugging sides down, thought deep front might make for bosom insecurity but risked it because I hate fabric near my neck and it clings like glue - no chance of anything falling out - proper swimmer, and already much worn. Five stars.

    Plunge swimsuit

    Purchased this for my holiday, little unsure as to whether it would be too revealing and offer enough support …. It wasn’t and it did…..swam in it everyday and felt good….if there could be one slight improvement it would be to make the body length just a little longer….

    Absolute perfection

    Everything about this swimsuit is just the best. For most of my life, I have avoided getting into a swimsuit at all costs. Finally I have found a swimsuit that is functional but also makes me feel completely fabulous. Thank you Deakin & Blue!
