If you ordered the wrong size or colour, you may be able to return or exchange your order. Sellers aren’t required to accept a return or exchange unless stated in their shop policies.
What should I do if the seller doesn’t accept returns?
If the seller doesn’t accept returns, and the item you received doesn’t match the Etsy listing, you may be able to open a case with Etsy. You can open a case if your order wasn’t as it was described on Etsy.
