Tapping into an increased interest in sustainable practices, fashion resale platform ThredUp and Brooklynbased clothing designer Zero Waste Daniel have launched a collection made entirely from secondhand garments and fabrics. The "ReFashion" collection takes the more than 100,000 secondhand clothing items sent to ThredUp each day and transforms them into clothing for resale with the help of Daniel Silverstein, the designer behind Zero Waste Daniel.
