While I know that there is abuse of the return option, and probably quite a lot, an immediate return is more likely to be because the item has simply been checked for fit and finish. Someone planning to wear something for a particular event before returning it is likely to have it delivered a few days in advance. I will not order items like footwear for mail delivery if I cannot return items that do not fit, and it is up to the retailer whether they want to trade with me on that basis.
