Tracksuit
Appearance
A tracksuit is an article of clothing consisting of two parts- trousers and a jacket. It was originally intended for use in sports, mainly as what athletes wore over competition clothing (such as running shirt and shorts or a swimsuit) and would take off before competition. In modern times, it has become commonly worn in other contexts.
Tracksuits as uniforms of certain subcultures
Tracksuits are the de facto uniform of the charva in north-east England and of the so-called dres in Poland.
