United KingdomI love the swimsuit. The first one I ordered wasn’t quite right and I was given some advice and got the right one. Such great help from the company, and very easy to return the garment.
United KingdomSuch a beautiful design.. I get so many compliments when I wear it .. plus it’s so comfortable and supportive..
United StatesGreat customer service
United KingdomThe best swimsuit I have ever purchased, love that I can reverse it and wear it both ways, patterned or all one colour. Would definitely buy another swimsuit from Deakin and Blue, they are the only company who cater for larger up top women who swim. Only negative I have is that the material around the leg opening is slightly loose, slides a little and isn't firm or feel secure. Would like a tighter leg opening, while being large up top I don't have an hour glass figure, my hips and legs are thin. But this issue would not stop me buying another swimsuit, I love the one I have purchased.
United KingdomNever in all my 52 years of swimming have I had a costume which fitted me so perfectly! It’s 2 in one and I adore the cobalt blue side, it’s difficult to decide which style to wear. The quality is perfection. My favourite make!!
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
Cassie's body story film"What happens in elite sport trickles down to the grass roots. Not only to young girls starting out in swimming clubs, but also to their coaches and parents and to amateur events.
But, when you stand at the start line of an open-water swimming event, you see women of all body types, sizes, backgrounds, ages and physical abilities. Judgements based on their appearances are hard-wired, but the truth is that you can’t tell who’s the fastest, hardiest or strongest swimmer by looking at them. Water is a great leveller enjoyed by everyone and anyone, and body discrimination has no place here."
MOVE BETTER
The X(-Back) marks the spotDesigned to give you confidence for swimming, surfing or simply sunbathing. Here's how:
1. Soft, supportive double-lined fabric
2. Built-in bust support & shape
3. Flattering scooped X-Back
4. Smart panelling for a sculpted shape
