How do I choose the right size?
Use our size guide to find your best fit based on chest, waist and hip measurements.
If you’re between sizes, we recommend choosing based on your preferred fit — snug for performance, or slightly looser for comfort.
Can I return swimwear?
Yes, swimwear can be returned as long as it is unworn and in original condition, with the hygiene liner and tags still in place.
We recommend trying items on over underwear.
How do I care for my swimwear?
Rinse in cold water after each use to remove chlorine or salt.
Avoid wringing or tumble drying, and allow to air dry naturally.
This helps maintain shape, colour and performance.
Is this swimwear suitable for regular swimming?
Yes - Maru swimwear is designed for regular use, with durable fabrics and a reliable fit that performs in and out of the pool.
