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.Jen Mason is the owner of Underground Vintage in Lewes, Delaware, a town on the Atlantic coast.She said that clothes in the store that do not get sold are provided to local people.They use the material for different purposes such as making blankets.Unsold clothes never go to waste, Mason said."We're a coastal community. So we're always thinking about how to be sustainable. And we also live on a peninsula, so, you know, it takes a lot of resources to get stuff out and back to here. So we're very much thinking about how to give something a new life."
