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-quality Italian lycra and typically run true to size, but if you are between sizes, we suggest sizing up for a more comfortable fit.

What is your return policy?

We offer a 30-day return window for all unworn swimwear. Items must have the original tags and hygienic liners intact to be eligible for a refund or exchange.

How should I care for my LOU Swim pieces?

To maintain the vibrancy and elasticity 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.

How long does shipping take?

Standard shipping typically takes 3-5 business days within the domestic region. International orders may take 7-14 business days depending on the destination and customs processing.

Are your materials sustainable?

Yes, LOU Swim is committed to ethical fashion. 80% of our current collection is crafted from regenerated nylon fibers sourced from recycled ocean plastics and ghost fishing nets.

Do you offer international shipping?

Yes, we ship worldwide! Shipping costs and estimated delivery times are calculated at checkout based on your specific location.
