    Favourite bathing suit!

    Love this suit so much, only feedback is that I wish they made the long torso in more colours!

    Perfect fit!

    This swimsuit is perfect. I really recommend it for women who have bigger bellies (like me). The extra length allows for everything to fit inside the suit nicely. I buy one once a year. I just wish you had nicer and brighter colours and prints like for the other swimsuits. I would buy at least 2 per season.

    Great swimsuit

    Love the fit! It’s hard to get a long torso in a swimsuit any more! I love Knix fabric, so silky smooth!

    Didn't work

    Im 5'11" 36F and i definitely needed the long torso. I tried the regular bc the long torso was out of stock and the crotch was uncomfortably tight.

    I wore this whilst on my period with no cup or tampon at the scandinave spa and I bled right through and I washed it many times in the sink. I don't know if it works better dry or you have to sit like a little angel. But I lounged on a chair after hitting the whirlpools and had myself a teenage flashback of staining everything I came into contact with. It was embarrassing.

    Im not sure I'm a fan, I might return it.

    Once piece wonder

    Finally a suit that properly fits this tall girly! At 5’10” I often find that one piece swimsuits are not long enough. The ‘girls’ aren’t properly supported and feel pulled down or too revealed. Not this suit, it’s perfect! Simple, classic look and fits like a glove with great support. So pleased I took a chance and ordered!
