You should NOT make returns so difficult. It discourages customers from buying from you if they cannot return merchandise. If you want loyal customers, make it easier to return items not hard. Do not haggle. Stop offering discount to keep merchandise the customer doesn't want. Just give them their money back. This creates an incentive for them to continue shopping with you and to buy more. Also, factually label the material of your products. Examples include, cotton, rayon, polyester, silk, nylon, ... Jersey does not tell me what the fabric is.
