Frequently Asked Questions

Everything you need to know before you dive in.

How do I find the right size for my ISMÊ swimsuit?

We provide a detailed size guide on every product page. If you are between sizes, we generally recommend sizing up for a more comfortable fit, or sizing down for extra compression and support.

What is your return policy for swimwear?

We accept returns within 30 days of delivery. Items must be in their original condition, unworn, unwashed, and with all tags and hygiene liners intact for a full refund.

How should I care for my ISMÊ pieces to ensure they last?

To maintain the elasticity and color of your swimwear, we recommend rinsing in cold water after every use and hand washing with mild detergent. Always air dry in the shade and avoid rough surfaces.

Do you offer international shipping?

Yes, ISMÊ SWIM ships worldwide. Shipping costs and delivery times are calculated at checkout based on your specific location and preferred shipping method.

Are your materials eco-friendly?

Sustainability is at our core. Many of our collections are crafted using regenerated nylon fabrics made from recycled ocean plastic and industrial waste without compromising on luxury feel.

What payment methods do you accept?

We accept all major credit cards (Visa, Mastercard, American Express), PayPal, Apple Pay, and interest-free installment options like Klarna and Afterpay.
