Frequently Asked Questions
Everything you need to know about your next favorite swimwear.
How do I find my perfect size?
We recommend checking our detailed Size Guide located on each product page. Our suits are designed with high-stretch Italian Lycra, but if you are between sizes, we suggest sizing up for a more comfortable fit.
What is your return policy?
We offer a 14-day return period for all unworn swimwear. Items must have all original tags and hygiene liners intact to be eligible for a refund or exchange.
How should I care for my ISMÊ SWIM pieces?
To maintain the vibrancy and shape of your suit, we recommend hand washing in cold water with a mild detergent immediately after use. Always air dry in the shade and avoid rough surfaces.
Do you offer international shipping?
Yes, we ship worldwide. Shipping costs and delivery times vary by destination and will be calculated at checkout. Please note that international orders may be subject to local customs duties.
When will my order be processed?
Orders are typically processed within 1-2 business days. Once your order has shipped, you will receive a confirmation email with a tracking number to follow its journey.
Are your materials sustainable?
At ISMÊ SWIM, we are committed to conscious fashion. Many of our collections utilize ECONYL® regenerated nylon, which turns ocean waste into high-quality, durable swimwear fabric.
