Swimwear care instructions.
To help maintain the quality and longevity of your ONNI swimwear, we recommend the following care:
- Rinse in fresh water after each wear.
- Hand wash or machine wash on a delicate cycle in cool to warm water.
- Use detergent free from optical whiteners or brighteners and wash with like colours.
- Lay flat to dry in the shade and ensure pieces are completely dry before storing.
- Avoid sun cream, tanning lotions, excessive chlorine and rough surfaces to help prevent discolouration, pulling or snagging.
With the right care, your ONNI pieces are made to be worn again and again.
I'm between sizes. What should I do?
We recommend referring to the size guide specific to the style you're purchasing to help find your best fit. Our size guides can be found on each product page.
Our bikini bottoms feature adjustable ties, allowing you to customise the fit. You can also size up or down depending on your preferred coverage, whether you like a little more or a little less cheekiness.
If you need help narrowing down your size, please contact our team for tailored sizing advice.
Do your bikini tops have cups or padding?
Our bikinis are designed without padding. Each piece is crafted from high-quality, double-lined fabric for a considered fit and feel.
If you need help finding the right style or fit, please contact our team for tailored sizing advice.

Our bikinis are sold as matching sets, pairing each top with its coordinating bottom.
Designed with adjustable ties, our bikini bottoms can be customised to your fit and preference, allowing you to find your ideal fit and coverage.
