We offer free returns and exchanges for USA orders within 14 days of delivery. We want you to be completely satisfied with your purchase and if you change your mind for any reason, there are a number of options available for you to return your item to us. 

Returned items must be unworn, unused and in perfect condition with all original tags and packaging intact.

All swimwear must be tried on wearing undergarments, the protective hygiene strip must remain in place and cannot be removed. 

If your return does not comply with these conditions we cannot accept your items and they may be rejected and returned to you. 

Full price items can be returned for a full refund, credit note or size exchange.

Sale items, including styles marked down during a flash sale, can be returned for a credit note or free size exchange only. 

For returns outside of the USA, we offer return shipping labels at a flat rate of USD$35. This cost will be deducted from your refund or store credit to cover the cost of the shipping label. You will be able to print this once you have submitted your return.

If you choose to send your return back to us via your own postage method, we encourage you to use a registered or traceable postal service as return parcels remain the responsibility of the customer until received by SIR if sent without a provided label.

Please note that our Customer Care office hours are from 9am - 4pm AEST and not available over the weekend but will send your label as soon as possible. 


Returns on sale items are not eligible for a refund. Sale items, including styles marked down during a flash sale, can be returned for a credit note or free size exchange only. 


We offer free and easy online size exchanges within 14 days from delivery for USA orders. 

Submit your online return through the portal and follow the steps to select a new size.

Exchange items will be dispatched free of charge once your return label has been scanned in transit by the courier.

Please note, as we are unable to hold your item until your package has been scanned in transit, we encourage you to drop it off as quickly as possible to avoid disappointment.  

If the size you are hoping to exchange for is no longer available at the time of processing, a refund or credit note will be issued depending on the item’s eligibility.


If your return is eligible for a refund, you will be refunded back to your original payment method, less the return shipping fee and any original shipping fees. Once the refund has been issued, you will be notified via email. Please allow up to five business days for this amount to appear in your account.


Credit notes are valid for three years from issue date, and will be emailed to you with a unique code to use online. If you have purchased an item using a credit note, you will be issued a new credit note as a return.


Final sale refers to items that are marked down during a special offer, or are marked to clear. Item/s marked as "final sale" cannot be returned for a refund or store credit, unless in the event of them being faulty. Items are eligible for direct size exchange, pending size availability. 

If final sale items are returned despite this policy, items will be sent back to you at an additional charge. 


Gift Cards are not eligible for return.


If you have purchased using Afterpay or Klarna, you will be refunded or credited back to your chosen platform. If you are receiving a credit note, you will continue to make payments until the original item is paid for and you will be issued a new credit note via email to use straight away.


Please allow up to 3 business days for your return to be processed. You will receive an email when our team has received your return and again when your return is processed. Please contact us at if you need assistance.


All items are quality controlled to a high standard before despatch, but if you receive an item that is not 100% right please contact us at with your order number and images of the fault or issue and we will work with you to resolve it as soon as possible. 

Please note that items which are damaged or as a result of normal wear and tear; by accident; failure to use in accordance with care instructions; or through misuse will not be considered faulty.
