30-Day Returns
You have 30 days from the delivery date to request a return. If 30 days have passed since your order arrived, we are unable to offer a refund or exchange.
Item Condition
To be eligible for a return, your item must be:
- unworn and unwashed;
- in the same condition you received it;
- in its original packaging, undamaged;
- with all tags still attached.
For hygiene reasons, we cannot accept returns on items that have been worn, washed, or altered.
How to Start a Return
Do not ship an item back before contacting us. Returns sent without prior authorization cannot be processed.
- Email contact@my-onesie.com within 30 days of delivery with your order number and the reason for your return.
- We will reply within 1 business day with a return authorization and the return address to use.
- Ship the item back using a trackable service and send us the tracking number.
Return Shipping Costs
Return shipping is paid by the customer, except when the item arrived damaged, defective, or was not what you ordered. In those cases we cover return shipping.
Original shipping costs are not refunded, and we recommend using a trackable shipping method. We cannot issue a refund for a return we never receive.
Damaged, Defective, or Incorrect Items
If your item arrives damaged, defective, or is not the item you ordered, email contact@my-onesie.com within 30 days of delivery with photos or a short video showing the problem. We will send a replacement or issue a full refund, your choice, and cover all shipping costs.
Exchanges
Need a different size or a different style? Follow the same steps as a return and tell us which item you would like instead. Once we receive your return, we ship the replacement at no additional shipping charge.
Refunds
Once your return arrives, we inspect it and email you to confirm whether the refund is approved.
Approved refunds are issued to your original payment method within 3 business days of approval. Your bank or card issuer then needs additional time to post the credit to your account, typically 5 to 10 business days. That final step is controlled by your bank, not by us.
Cancellations
You can cancel your order for a full refund at any time before it ships. Email contact@my-onesie.com with your order number as soon as possible.
Late or Missing Refunds
If you have not received an approved refund after 10 business days, check your bank account, then contact your card issuer, since processing times vary. If you have done both and still have not received it, email contact@my-onesie.com and we will follow up.
