I have a problem. I sold a NWOT Burberry Brit XXL shirt, listed it as slim fit and provided all measurements (17 inch collar, etc.) and I don't take returns. The buyer messaged me saying it's a kids shirt, which is absolutely impossible I wear a US 44 suit and it fit me a bit big, and he wants to return it. I think he has buyer's remorse or didn't read the listing and absolutely do not want to refund him his $94, what do you guys think?
