    Love it

    5’2” 144lbs 34DD and a size 6 petite, 2 kids, a little floppy here and there with some loose skin and this bathing suit put everything right back where it was when I was 20! I don’t wear spanx or shapewear because it never fits well. They could learn a thing or two from this company. I guess I’ll be sporting my bathing suit all summer under all my clothes cause where did this figure come from?! I’m loving it!

    Love as a swim suit or everyday bodysuit

    Honestly I love this suit, I wear swimming and as a regular top. I’m normally and xs or small in shirts, dresses, and I’d say I can probably wear both sizes probably as well in this suit but I did end up getting an xs. I love how body contouring it is, snatches me in.

    Love it

    I absolutely love how sleek this suit is. I haven’t worn it in the ocean yet but I am going to wear it as a regular body suit tomorrow. It’s soo flattering, it accentuates all the curves in my body and I am thrilled. I may have to buy the long sleeve version next!

    My dream swimsuit is real!

    Had a wonderful shopping experience in the Canggu store recently, and I’m so happy I purchased this swimsuit - The material is soft and luxuriously high-quality, and I feel great wearing it knowing I am supporting a sustainable brand with Bali-made products 🩵🌊 The olive green colour is lovely and matches my resort sarong as the perfect combo - but I wish I could buy all the colours! I feel confident in this swimsuit as the material and cut is super flattering, and it stood the test out snorkelling in the choppy Nusa Penida waters! I hope to continue to grow my collection of Ocean Soul pieces and keep raving about this brilliant brand!

    Perfect for any age!

    I am 61 years old and I feel amazing in the suit! It is my third one- I own one in black and one in white! I receive many compliments which boosts my confidence in still feeling like a woman and not matronly. I wore the white one to Greece and it was perfect! Even my daughters loved it on me! So happy to have found your company- I am a forever customer!

    Amazing swimsuit

    This swimsuit fits perfectly and the fabric is amazing quality. I’ve worn it snorkelling, kayaking, scuba diving and it has never slipped. It also looks great as a top after a swim and I love the style.

    I love this piece so much. Wore it for surfing and it fits so well, so snug, I wasn’t worried about anything showing. Feels like a second skin to me and absolutely no regrets.

    FAQS

    Absolutely. The Mentawai one piece is designed for both active water use and lounging. The UPF 50+ fabric retains its shape and colour in chlorine and saltwater, making it perfect for swimming, surfing, and snorkelling.

    Rinse in cold fresh water after each use, especially after exposure to saltwater, chlorine, or sunscreen. Hand wash with a gentle detergent and lay flat to dry in the shade. Avoid machine washing, tumble drying, and wringing to preserve the fabric's stretch and UPF protection.

    You can adjust the fit of each surf suit by hitching the leg high up on your hip, which gives you brief coverage. Or pull it down on your hip for more coverage.

    Our one piece swimsuits are intentionally designed without padding. Thanks to the sculpted, panelled design, double lining, and a firm, supportive fit, there's no need for built-in cups. The one piece suit naturally holds you in, flatters your shape, and gives you all the support you need—without any shifting or bunching that often comes with padding.

    If UPF protection is important to you, opt for the darker colours. The Sulawesi in Midnight provides the most UPF block out, due to the dark colour of the fabric and long sleeves. Do keep in mind, the mesh on the side is not UPF. If you want full block out, please use an SPF on the side of your body.
