Great fitting and looking swimsuit.

I can never find a swimsuit that fits well. This one is very simple and flattering. I wrestle with tummy control costumes and have to get my husband help to heave them up! - and I’m only a size 10! This one is perfect and I’ve bought both colours.

Good fitting swimsuit

Good fitting swimsuit, true to size. Not lots of shaping but enough. Haven’t used it much so far so not sure about how long lasting it is but hopeful that it will be as it’s supposed to be chlorine resistant.

Whilst the price is a little high, I like the fit and it’s perfect for an Aqua class. The fabric is lightweight in comparison to other costumes and the fit was true to size
