    Great Fit, Needs Higher Cut Leg

    I love my swimsuit from the waist up.... I did however feel the leg was cut too low and had it altered to be higher. It's now just perfect. The lower cut on the leg felt a big old and frumpy to be honest, but once lifted about 20mm on the hips it made the world of difference and drastically elongates the leg. Just feedback for future.

    Great for bigger busts!

    I have never bought a swimsuit without underwire before, but after reading so many positive reviews, I was very keen to try. I ordered a 12 in order to fit my 10F cup bust and was very happy with the fit. Even though I live in Australia, I am generally self conscious about putting on a swimsuit - this has definitely helped ensure I am supported in all the right places. To the beach I go.......!

    Amazing - Love This Swimsuit!

    This swimsuit is so stunning & flattering. I'm a very tall, solid-framed size 14-16 with a large DD/E bust, and I feel absolutely beautiful in this suit. It rides up on the bum a little more than I like when I'm in the ocean, but that's a small price to pay for such a beautiful fit.

    I've only worn it once thus far, and would like to see how it fares long-term with regular exposure to the ocean water, but overall I'm very impressed.
