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

Hi Julie, We're so sorry The One didn't fit as expected. We can see that we've never done an online fitting with you, we'd highly recommend doing one so we can confirm your fit. We'll arrange for one of our fit specialists to contact you shortly. the — fold

Great fits. Amazing service

Following some reviews on here, I had ordered my swimwear a size up from what I usually am and couldn't be happier with the fits. This is the first brand I found that does nice design with lovely materials that fits great -and I tried a lot!- Further, the customer service is exceptional. I had a few issues with my order being delivered to the UK during COVID times and Stephanie and Carly were incredibly helpful. Thanks so much for your help and producing such lovely and well fitting swimwear.

Beautiful piece! I had to exchange for one up in size and down in cup. I'm 8G in the Base but 8G in the One was short in body and generally too tight pulling boobs down and causing the bottom bit to dig in). 10ff is a much better fit. The cut is quite revealing, like all the photos suggest. Both boobs and bum get little coverage so it won't be my only one piece, having said that, it is beautifully made and the cut is flattering, making legs look long and exposing just the right amount of back whilst still being supportive. Customer service was very good, helpful and prompt. Thank you team Fold, love your work.

The One - Black

This cosi misses out on a 5 star because of it’s length on my long torso. The support however is excellent, the cut beautiful and the make is quality. Definitely my favourite one piece swimsuit I have ever owned. I’ve never felt so stylish, well supported and confident at the beach.
