Stylizated folk costumes of West Slavic countries (Poland, Czech Republic, Slovakia). From the left:
Podhále region, Southern Poland
Kyjov village, Slovácko region, Moravia (Eastern Czechia)
Liptovská Lúžna village, Liptov region, Central Slovakia.
I just realized ones of the most popular folk costumes in those two countries are right on Slovak borders, haha XD
