    For all bust sizes!

    This fit is great if you do have a bigger bust, it holds you in and you can easily swim without fear of anything coming loose. It also gave great support through the tummy.

    Very disappointed

    I am a return customer and until I ordered this swimsuit I thought this company could do no wrong. I have referred multiple people to this brand and this was my third purchase. I almost never write reviews but feel compelled to for anyone with a figure bigger than a size 10- it fits terribly. I WAS actually incredibly nervous about the bust area (as I have E sized cups); the cups actually fit great; it was the bodice that was the let down. The seam sits right at the belly button and unless you have a flat stomach; it literally gives you an extra stomach roll. I am having to send them back and I am so incredibly disappointed. The square neck swimsuits have magic in them and I just assumed these would too. Alas they do not. Avoid if you’re a size 12-14 and you’ve had kids.
