Nothing new here. This has been our biggest complaint during our 15 years of selling. That is, buyers claiming NAD or defective due to fit. In 15 years not one of our customers who do this have ever gained weight. Rather, the reason the bra does not fit is because it is defective and “runs small” or, our favorite, “not true to size.” Whose size? Who made these buyers fit experts? So, our advice in this matter is to remember, when debating or defending, the term “buyer’s remorse.” Also, put as much as possible into your listing and policy page regarding sizing. For whatever reason, eBay and Amazon both have not addressed the size issue. Does an item not fitting equal defective because the buyer claims “I have always worn this size, therefore…”? The answer is “No.” The size of the item is the size printed on the label and according to that particular manufacturer. There is no global sizing standard but this “buyer’s remorse” issue simply has not been addressed. For us, it is right up there with the USPS tracking stating “delivered” but yet this is NOT proof of delivery. While this is a different issue we mention it for the sake of comparison in regard to frustration levels.
