Returns Policy:

You may return new, unworn items within 30 days of delivery for a full refund. Return shipping is never covered unless a product was damaged or was shipped incorrectly. In order to be illegible for a return, the following conditions must be met.

  • Buyer must pay return shipping and be able to provide a valid tracking number if requested.
  • Item(s) must be in the same new condition that it was in when received, with all original tags and hygienic liners in place.
  • Item(s) must be free of any perfumes/fragrance, orders, and deodorant/lotion marks. Any swimwear returned with pet hair on them cannot be accepted under any circumstance. 

All exchanges are subject to Sunnyside Swimwear's approval and may be sent back without return eligibility if the above conditions are not followed.



Customized pieces are swimsuits that are altered in any way by the request of the customer to something other than the original product pictured.

You should expect to receive your refund within two weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 7 business days), the time it takes us to process your return once we receive it (1 to 2 business days), and the time it takes your bank to process our refund request (2 to 6 business days).
