Folk costumes in Poland varied by region and were most prominent in the late 19th and early 20th centuries as peasants gained more freedom and wealth. Different regions had distinctive costumes influenced by climate, economics, history, and sometimes military uniforms or aristocratic fashion. Today, folk dance companies and some restaurants preserve traditional Polish folk costumes to celebrate regional cultures for tourists and audiences.
