The article deals with the analysis of the lexical items denoting parts of the male and female Lemko costume (trousers, skirts etc.). The investigation is based on the names of the elements of the traditional garment fixed in the dialect dictionaries, atlases, in some ethnographic research publications and written down in fieldwork. The origin of the analyzed names is investigated in this paper. There are loans from such languages as Hungarian, Slovak, German, etc. The similarities of the names of clothes item, fixed in the Carpathian Mountains, areas of dwelling of Boiko, Hutsul, Bukovina, Transcarpathian ethnic groups are compared in the article. We noticed some formal and semantic differences in the nomination of the elements of the traditional garments in the region near the San River. There are differences in nomination of the parts of folk costume within the Lemko region, not only between the south and north parts, but also names change from west to east.
