You donu2019t sell clothes to Goodwill, St. Vincentu2019s, Deseret Industries, or other non-profits, you get a receipt for your donations. You put the clothes into a box or a bag and get a receipt that you may fill out the garage sale value of your clothes and use it for your tax donations.If you want to sell used clothing, go to a consignment shop. Find out from them how they have their sales set up. Some will buy your items outright, others will have them for sale, and after a period of time, either you get a percentage of the sales for the ones that sold, and you take back the items that didnu2019t sell. Consignment shops are generally individually owned, so each place has its own rules.If you want to sell clothing that youu2019ve made, you may check out boutiques, craft malls, Saturday markets, holiday fairs, etc.
