Photos by a friend of mine, who focuses on photographing various aspects of Slovak folk culture, including folk costumes. This one is from Hont region and more can photos be found here: http://mitosinkovie.blogspot.com/2012/04/folklore-in-botanic-garden-janka-is.html. Check out her flickr or etsy shop as well!
Update: I have to note that the skirt is actually not from the same region as the jacket, and also that this project of her has no intentions on documenting or researching folk traditions. For her it serves only as source of inspiration and a as a playful theme!
