DON'T LOVE IT?
We want you to feel like your best iteration in our intimates. That’s why we offer FREE and EASY returns and exchanges. Our goal is to make you happy by creating products you love to wear. Bras + undies that go unworn or end up in the back of your underwear drawer aren’t sustainable – so if the fit’s not quite right or you don’t love your order – no problem, we’re here to help.
Return eligible items within 30 days of delivery. Items must not be washed, worn, or damaged by customer, and they must have their original tags attached. Final sale items are not returns eligible.
RETURN STEPS
-
Start your return on our Returns Portal using your email or zip code AND order #.
-
Select which items you would like to return or exchange.
-
Select your preferred refund method (if not an exchange).
-
Print your label and attach it to the top of the package OR use the provided QR code, then drop it off at the shipping service provider.
-
All returns must be sent back within 20 days of receiving your return shipping label or QR code. Returns that are not sent back within that window will not be accepted by the shipping service provider.
TRY-ON POLICY
To keep our intimates safe, clean and like new, please wear your own undergarments underneath when trying on any of our undies. We purposefully don’t use liners to reduce our plastic consumption, so please take extra care while trying-on, so the undies stay fresh and fabulous in case you need to return or exchange them. Any undergarments that have been worn or washed cannot be returned.
REFUNDS
You will be notified once we have received and inspected your return. If approved, you’ll be automatically refunded to your chosen method of refund. Refunds and store credit will be issued net of return costs when applicable. Unapproved items will be returned at your expense. Please allow 10 business days for your return to be processed from the date we receive it. If refunding to your original form of payment, please remember it can take some time for your bank or credit card company to process and post the refund too. If more than 10 business days have passed since we’ve approved your return, please contact us at team@iterationera.com.
INSTANT EXCHANGES
If you’re in a hurry to get your exchange, we offer the option of instant exchange via our Returns Portal. If you select an instant exchange, an order for your exchanged items will be created immediately (as opposed to waiting until we receive your original items to begin processing). A $1 hold will be placed on the credit card on file while the exchanged items are shipped to you. You will have 7 days to drop off the original items at the shipping service provider. Once the original items are received, the hold on your card will be removed. In the event the original items are not returned, your card will be charged for the value of the exchanged item.
