I love this bikini. It fits really well and the quality is so nice.

I absolutely love the bikini bottoms! They have a silicone grip on the inside that keeps them securely in place, so they don’t shift or ride up while swimming. They feel really comfortable, stay put, and give me confidence in the water. Such a thoughtful feature that makes a big difference!

Great bikini for swimming! It stays in place while I swim. The fit feels secure, though I’d recommend adjusting the top straps to a tight fit before wearing it, as they can be loosen while swimming. The fabric is supportive and comfortable. Definitely recommend it if you’re looking for a practical yet stylish bikini set.

Gorgeous bikini. I love to see it’s made of recycled material. The material is super soft and stretchy but also durable. It fits like a glove and am very pleased with the coverage. Would reccomend to anyone out there looking for high quality wearable swimwear at a very reasonable price. Thanks so much and good luck! ☺️

This bikini was a big deal for me, because it was my first time showing my belly button since I hit puberty. I was a little nervous of the fit on my hips, but I find the high cut to be perfect for my wider hips. Super flattering, really secure, and a gorgeous colourway. Received lots of compliments at the pool!

I wasn't sure how the top would fit the girls, but it keeps them secure during training without feeling restrictive. Love this bikini so much, I got the set in a different colour!

The bikini stays on during open water and pool swims. It has a comfortable fit on the shoulders and doesn’t cause strain.

So secure even when doing a “proper” training session! Looking forward to wearing her on holiday AND for some serious swimming!

I love this top. I bought a 32, and it’s very comfortable and sporty. I’m usually between a small and a medium in all top sizes; bra size is 34c. I own a 32T one piece from instant swim and it’s too loose and long, the next one I’m buying will just be size 32.

Absolutely love my new two piece. Both top and bottoms fit great, secure enough to surf in. Can move the straps around to help with tan lines. Love it honestly considering buying in black because I love it so much!!!
