    Modest swimwear that sculpts, protects and stays on

    Ocean Soul's modest swimwear gives you full coverage without giving up style or performance. Our long sleeve one piece swimsuits, long sleeve bikinis and rash vests cover your arms, shoulders and torso, so you can swim, surf, snorkel or spend all day at the beach feeling confident and protected.

    Every piece is made from premium recycled Italian ECONYL® fabric with UPF 50+ sun protection. Clever panelling and a double-lined structure smooth and shape your silhouette with no padding, and a secure fit means no riding up, no gaping and no adjusting.

    Why women choose Ocean Soul for full coverage swimwear

    • Full coverage, flattering fit: long sleeves, high necklines and a cinched waist that defines your shape.
    • Designed to stay on: tested by surfers and freedivers in real ocean conditions.
    • UPF 50+ sun protection: blocks at least 98% of UV rays across everything it covers, so you need less sunscreen.
    • Built to last: resists chlorine, salt water and stretching, backed by our 12-month warranty.
    • Sustainable and ethical: made in small batches in Bali from regenerated fishing nets and ocean waste.

    Modest swimsuits for every kind of day

    Choose the Sulawesi long sleeve one piece for maximum coverage with a sleek, feminine cut. It's our best seller. For the most coverage, the Sulawesi Midnight T adds thumbholes that extend protection to your hands. Prefer two pieces? Our long sleeve bikinis and rash vests let you mix and match coverage your way.

    Modest swimwear FAQs

    What is modest swimwear?

    Modest swimwear covers more of the body than a standard swimsuit, usually with long sleeves, a higher neckline and fuller bottom coverage. Women choose it for personal, cultural or religious reasons, for sun protection, or simply to feel more comfortable and confident.

    Are long sleeve swimsuits good for swimming and surfing?

    Yes. Ocean Soul long sleeve swimsuits are designed for active use. They stay secure through paddling, duck dives and ocean swims, and the fabric dries quickly and won't bag out when wet.

    Is modest swimwear see-through when wet?

    No. Every Ocean Soul swimsuit is double-lined for opaque, smooth coverage in and out of the water, including our white styles.

    How do I choose the right size?

    Check our size guide. Our suits are designed to fit snugly so they stay in place in the water. If you're between sizes, our team is happy to help.

    This is the most durable swimwear I've ever found for diving and surfing! The zipper does 👏 not 👏 quit, the colors are gorgeous, and the suits keeps their shape and color even after years of use.

    Made for the sunshine, sea and amalfi!

    Wore the Sulawesi in Nautical while cruising along the Amalfi Coast, and it couldn’t have been a more perfect fit for the occasion ☀️💙

    The fabric feels buttery-soft and supportive without being restrictive! It’s one of those swimsuits that actually flatters and moves with you. The long sleeves kept me sun-safe, and the cinched waist gave such a sleek, confident fit.

    That said, if you’re tall like me, I’d recommend sizing up for a little extra length and comfort. The fit still hugs in all the right places, just with a bit more room to stretch and relax.

    I also love that it’s sustainably made from regenerated nylon and crafted ethically. A timeless, feel-good piece that’s as stylish as it is conscious 🌿

    Absolutely in love! :)

    From the moment I unwrapped this beautifully wrapped Swimsuit I was in love. The quality and feel of the material is so nice and it looks really flattering on :)
    I'm happy I listened to the recommendation of sizing up for the "Midnight" colour and chose a size L, although I'm usually a Medium.
    For reference, I'm 164cm tall, 95cm bust, 72cm waist and 100cm hips.

    I've been wearing it on every single Freedive for the past months and I couldn't be happier. I was eyeing this suit for almost a year and I'm so so happy it's finally in my life now ❤️
