We are sorry to hear that.
But you are in luck and can return any item(s) that meet our Returns and Refunds Policy requirements and are within 30 days of receiving your order. Within this time-frame we are able to process a refund; and you can re-purchase in the correct size. We unfortunately are unable to accept exchanges and anything marked as "Final Sale" in non-returnable/non-refundable.
You will find our Returns Portal to lodge your return here.
The best thing to do is to check out our full Returns and Refunds policy and send an email to returns@bigandlittledogs.com if you have any unanswered questions.
