Yesterday, I was visiting The Silesian Festivities (Śląskie Gody) in the Silesian Heritage Park (part of the Silesian Culture and Recreation Park). The Silesian Heritage Park presents a folk art from the whole Silesian Province, so not only from my region, but also from mountains and from Zaglembie -- I am not an expert at folk art, but I am sure that the men's costumes (above) are correct for my region, so I think the women's costumes are also from 'here'.
I've used 'national costumes' proposed by dictionary. But maybe better is folk dress or traditional garment, because the costumes are strictly regional -- their come from Upper Silesia. Even in the Silesian Province we have different costumes -- in mountain area, and in Zaglembie. In whole Poland there are many regional folk dresses.
