Americans in greater numbers are buying used clothing. Fans call it vintage clothing. They believe buying old, used clothes can save money. They also consider it good for the environment and stylish. Vintage stores sell clothes from previous time periods. The stores often carry famous brands and sell them at low prices. Vintage clothing has been on the rise for about 10 years. It is driven largely by a new generation of people who are concerned about sustainable ways of living. That means they want to waste less and use natural resources carefully. In 2018, the United Nations said that the fashion industry causes "around 10% of global greenhouse gas emissions." The U.N. said the industry uses more energy than the airplane and shipping industries combined.
