Customs and duties are taxes or import fees charged by your country’s government when a package arrives from abroad. These fees are not included in your order total from SIMS Swimwear and must be paid by the customer if charged at delivery.

Customs fees vary depending on your country, the value of your order, and local regulations. To get an estimate: - Check your country’s import guidelines online. - Use online calculators like SimplyDuty or DHL Duty Calculator for a rough idea. - Contact your local customs office for the most accurate information. Unfortunately, we’re unable to predict or cover these charges, as they’re handled entirely by your country’s customs authorities.

Always hand wash your swimwear in cold water using a gentle detergent or mild soap. Avoid bleach, harsh chemicals, or fabric softeners, as they can damage the fabric and elasticity.

We recommend avoiding machine washing and tumble drying. The heat and agitation can cause the fabric to stretch, fade, or lose shape. Instead, gently squeeze out excess water and lay flat to dry in the shade.

We currently offer sizes XS - XL across all our swimwear styles. To find your perfect fit, check out our Size Guide which includes detailed measurements and fit tips. If you're between sizes or unsure, we recommend sizing up for a more comfortable fit. Still unsure? We're happy to help! Just email us at connect@simsswimwear.com and we'll guide you.
