Sportswear, as its name implies, is the clothes worn during sports. This kind of clothes generally have the characteristics of sweat absorption and breathability, because they will sweat when exercising, and their bodies will heat up, which is more elastic and conforms to many people's bodies. In addition, there will be many large-scale movements during exercise, and ordinary clothes will be stretched, but sportswear has good ductility and will not be stretched because of too much movement during exercise. People who go to the gym or have the habit of running in the morning will wear sportswear.
Sweater is a kind of fashionable clothing, which was first used as a tool for refrigeration workers, and later favored by athletes, and finally developed into one of the clothes that the public will wear. Its function is to keep out the cold and keep warm. Of course, there are also sweaters in summer now, which will be cooler to wear. Sweaters give people a more casual feeling and can reduce their age, so they are suitable for most people to wear. Even children have children's sweaters.
So the difference between sweaters and sportswear is quite big, but it is also easy to distinguish, and the two kinds of clothing will not be confused.
