A Beautiful Swimsuit

I am in my late 50s and haven't bought bathers in nearly a decade. Although I swim every summer in pool and ocean. I didn't really care how I looked to be honest. But when I put on The One, in that perfect shade of navy, honestly I thought to myself, I am pretty fetch. The fit, the perfect uplift, and the quality of the fabric was very... confidence building. Thanks The Fold.

Great swimwear

I always find shopping for supportive swimwear a nightmare! I’m very happy with this one! Lovely simple design, great fabric and supportive.

Beautifully designed and executed

After reading many reviews. I took the plunge and purchased my first The Fold piece. I have a long torso and after recently having my first baby by bust has been larger than previous summers. The one piece has been incredible. It has given me the confidence and support all other swim suits have failed to provide. I have found the cup size true to size. The only thing I have noticed is after a morning at the beach squatting down, picking up and playing with my daughter is that the bottom of the swim suits begins to ride up a little bit. Otherwise I cannot recommend this piece enough

Great Quality

The fabric is amazing, very supportive and I love the double lining. Unfortunately I had some issues with the cup size but I don't want to exchange again. The staff are very helpful to discuss and fit concerns with! I'm about a 10H cup size and 14 in the bottom so ended up buying the 14DD (the 14FF was waaaay too big in the cup so I'd rely more on the conversion chart than the fit quiz if you know your sizing). I was initially worried that the 14 was too tight and digging in slightly at the bottom however the item stretches a little once you've been in the water. If you're bigger on the bottom I personally wouldn't size down. Overall pretty happy with it, I'd just use the try before you buy in future.
