Size Guide
At Mari Swim, we understand the importance of the perfect fit when it comes to swimwear.
Our suits are designed to be sculpting and to stay on during all your activities.
This is a guide to our sizing - it is not exact measurements.
If you find yourself between sizes, or prefer a looser fit for your swimwear, we recommend sizing up.
Feel free to send us an email at hello@mariswim.com.au for assistance in finding your perfect fit!
