Frequently Asked Questions
Everything you need to know before you dive in.
How do I find the perfect fit?
We recommend checking our detailed Size Guide located on each product page. Our swimwear is designed to be true to size, but if you are between sizes, we suggest sizing up for a more comfortable fit.
What is your return policy for swimwear?
We offer a 30-day return window for all unworn items. For hygiene reasons, all returns must have the original tags and hygienic liners intact. Items showing signs of wear or missing liners will not be accepted.
How should I care for my Sink Swimwear pieces?
To ensure longevity, rinse your swimwear in cold fresh water after every use to remove salt or chlorine. Hand wash with a mild detergent and lay flat in the shade to dry. Avoid machine washing or tumble drying.
How long does shipping take?
Standard shipping typically takes 3-7 business days within the domestic region. International orders may take 10-15 business days depending on the destination and customs processing.
Are your materials eco-friendly?
Yes, we are committed to sustainability. A majority of our collections are crafted using recycled nylon fabrics such as ECONYL, which repurposes ocean waste into high-quality luxury swimwear.
Can I change or cancel my order after it's placed?
We process orders quickly to get them to you as fast as possible. You can request a change or cancellation within 1 hour of purchase by contacting our support team at support@sinkswimwear.com.
