As a small independent brand, we are currently unable to offer refunds or exchanges. We appreciate your understanding as we grow! Please reach out before purchasing—we’re happy to help with sizing and fit advice to make sure you feel confident in your order. Due to the limited nature of our small-batch releases, all items are final sale.

If you receive a faulty or incorrect item, please reach out to us at hello@sirencoreswim.com within 48 hours of delivery with photos and your order number. We’ll do our best to resolve it quickly.
