Frequently Asked Questions
Everything you need to know about your ISMÊ SWIM experience, from sizing to shipping.
How do I find the right size for my ISMÊ swimwear?
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 for swimwear?
For hygiene reasons, we accept returns within 14 days of delivery only if the original hygiene liner is intact and all tags are attached. Items must be unworn, unwashed, and in their original packaging.
How long will it take to receive my order?
Standard domestic shipping typically takes 3-5 business days. International orders can take between 7-14 business days depending on the destination and customs processing.
How should I care for my ISMÊ SWIM pieces?
To maintain the quality of the fabric, always hand wash your swimwear in cold water with mild detergent after use. Avoid machine washing, tumble drying, or contact with rough surfaces and excessive chlorine.
Are your swimsuits sustainably made?
Yes, ISMÊ SWIM is committed to ethical production. Many of our collections utilize ECONYL® regenerated nylon, which is made from recycled ocean plastic and ghost fishing nets.
Which payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, American Express), PayPal, Apple Pay, and interest-free installment options like Afterpay and Klarna.
