Wave-O is an Italian brand based in Milan focusing on fashionable t-shirts. In March 2014, Wave-O collaborated with the ECONYL® brand to present a new collection of t-shirts made with the sustainable Nylon yarn, merino wool and Swarovski crystals. The “Be More Eco” collection consists of brightly colored t-shirts with witty sayings such as, “BE COOL BE ECO”, “PLASTIC LOVE” and “I WEAR RECYCLED FABRIC”. The t-shirts draw attention to the sustainability movement with their loud phrases referencing recycling and being more ecological.
