The article talks about development in thread use, composition, the colourfulness of embroidery and many other changes that are characteristic for festive traditional clothes from the beginning of the twentieth century up to contemporary times in Pohorelá at Horehronie (Central Slovakia). The original cotton embroidery thread from the 1960s started to be replaced in the embroidery on clothes and thin thread for knitting. The colourfulness of the embroidery was supplemented with gaudy neon colours in the 1970s. The dimension of the embroidered surface significantly increased – threefold on the male shirt, the connection of the sleeve to the shirt sixfold etc. The embroidery is sometimes not applied directly to the shirt but rather on a strip of material then sewn on the shirt. Since the 1950s decorating the embroidery on the clothes with flitters became popular, and this is currently very rich, especially on wedding head caps.
