It's always possible that we grabbed the wrong size or color when your order was packaged - we're humans, after all. Be sure to review the item description on your packing slip to verify that the item we shipped is the one you received. If its not a match let us know asap so that we can get this fixed.
Your Chivery order confirmation email will show what was purchased, and will include size, color, gender, and other pertinent information. Please note that if there was a mistake made at checkout, i.e. you meant to order a small, but put a medium in your cart by accident, we must process this as an exchange. Just reach out to our Customer Care team if this is the case.
