Beat one piece on the market

Stop looking at any other one piece bathers, as you have now found the most versatile, practical but sexy, beautifully made one piece out there! From the moment I tried it on, I not only felt super comfortable but it’s also super sexy! It is so so flattering, being such a great cut.
Can not recommend highly enough!

Ocean Soul Bali Sustainable Swimwear

Sustainable Swim

We value slow fashion over fast with a focus on sustainable fabrics and ethical production. Crafted from regenerated nylon that is designed to last twice as long as your regular swimsuit. Our swimwear is designed & made in Bali with love, with 10% of each sale donated to those in need through our Giving Back initiative.


We line all our snow white surf suits with a beige econyl sustainable fabric, to prevent them from becoming transparent.

Our one piece surf suits do not have built in support. They are double lined and are a firm cut, designed to hold you in. We have customers from a AA-D that are happy with the support with our surf suits.

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.

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.

All our one piece surf suits are designed to be like shape wear and hold you in. If you prefer a more relaxed feel, size up and if buying the midnight go up two sizes, as the black colour doesn't have as much stretch due to the dying process.
