Here’s what consumers have asked with answers from Etsy staff and previous consumers.
Look at sellers terms of service and policies. It varies... some sellers will allow returns; some won't. Some require you pay return shipping; others don't. Some sellers have a time window too and won't accept the return after a certain number of days has passed. Send the seller of that specific shop a quick message explaining your concerns and questions that way you have evidence after purchasing
I believe this depends on each seller. Etsy is simply a platform for sellers, and often does not have any direct involvement with orders short of processing the payment. Certain items cannot be returned for safety and hygiene reasons, and sellers can refuse to do anything other than exchange. Contacting Etsy may or may not change the results.
Etsy support is useless... they are on the sellers side they take down negative reviews warning other buyers... it's a scam... they're global community initiative is a marketing ploy... I hope your get your item... I really do I stopped using them after 10 years as a buyer it took one bad event and never again.
