Absolutely estatic

I am generally a 12F but always size up for swimwear so got 14F - both the one piece and bikinis are so flattering! I am so so happy and going to order a red one too. Thank you!

Finally, an amazing one piece!

I've always been super hesitant to purchase swimwear online because of my size but after reading other reviews on this style I thought why not! The full (but hidden) underwire is so supportive and I love that the rest of the swimsuit actually fits my body, unlike other 'large' sizes I had to buy because of my bust! I love the slightly lower back as well, creates a lovely feature but isn't too low that it's impractical. One thing for me though, is that the fabric on the bust could come up a little higher to be sure that there would be no accidental slippage or spilling over! When I emailed to get some advice, I had a lovely customer experience with the online team xx

After 10 years of looking for bathers Ive found my match! I have had a size F cup since I was sixteen and have never found a pair of bathers to fit. The items i brought flatter my body and make me feel comfortable with my larger bust, as I always wished they were smaller to fit in bathers. A perfect fit thank you for your smart designs. After years of bather searching I can finally have a comfortable summer!

Almost there!

Great design, supportive, simple, chic. Top quality fabric. The only issue I have is that the underwire rides up a bit high under the armpit no matter how I adjust the straps. I went for a size up based on several reviews that mentioned this style was on the small side, but I probably should’ve gone for my usual size in the bodice (10). The cups fit well though. Overall it’s a great swimsuit!

We're so glad you love The One! The fit is true to size so we're not surprised the size up isn't quite right. Next time we'd recommend going with your regular size :) the — fold

Beautiful simple design, not good if you need support

The design is beautiful and if I had smaller breasts and needed less support, I would have kept it. Unfortunately it didn’t give me that and the straps are just too thin to do the job. I wish there was a version of the swimsuit designed for women with big boobs

Hey. Our one piece is specifically designed to support D-G sizes, so we think maybe you had the wrong size. Let us know if you’d like to do an online fitting to figure out what went wrong and how we can better support you. the — fold
