I ordered this shirt, which became lost in the mail en route to me. I waited extra days to contact the company in case the item should appear, but it never did. I then reached out and received a response from a very nice representative who asked me to wait extra time to determine if the item was really lost. I did so. I then reached back out and indicated it had not arrived. I was offered the option of a replacement or refund and requested a replacement. Then nothing happened. I sent a 2nd email requesting a replacement. Nothing happened again. As far as I can tell, this lovely shirt exists only in theory, as I have not seen one single thread.
We're so sorry your package was lost in transit! We completely understand how frustrating that is.
We did reach out twice to offer either a full refund or a replacement, but unfortunately, we never received a response confirming your preference.
We've now submitted a replacement order at no additional cost and will send tracking information as soon as it ships. We truly appreciate your patience and hope you love your shirt when it arrives.
