Not sure about size?

    Wonderful swimming costume

    Lovely costume, great structure and fit, I hadn’t swum for 15 years and was a little nervous, then as I stepped out of the changing rooms said what a lovely colour (plum) my costume was! I felt fantastic. The swimming was great too!

    I have already had someone ask me where I got my swimsuit from. She had been unable to find a swimsuit that could give the support the straps give across the back.

    So flattering

    I love my new costume. It is most definitely the most flattering costume I’ve owned. It feels supportive and I love the cross-back design. The only issue is that it rides up my bum with every movement. I have heard this is a common issue which is a shame… hopefully something that can be improved with future costumes, because other than that it is gorgeous

    Lovely swimming costume

    You really do have to wriggle to get it on, but providing you have done the measuring it will fit and it looks good. Sadly what with Christmas and having had Covid I have not had a swim in it yet. I am looking forward to finding time for a swim and looking forward even more to swimming in a lake again. Might need to wait for the water to warm up a bit first though.
