The paper presents the results of the study of the techniques of joining the parts of traditional shirts. The analysis of museum pieces presents various techniques for combining landmarks with a functional and aesthetic role. In traditional holiday women’s shirts, the joining of of parts on the lines arranged in the accessible visual perception area techniques of joining by keys of different complexity, integrated solutions of edge processing elements by crocheting and joining techniques by keys („cheițe”) were used. The joining lines of the parts arranged in areas with low visibility show applications of simple joining techniques such as stitches before the needle, after the needle, the processing of the edges of the parts with scalloped points. Traditional men’s holiday shirts used the joining of keys in some models, but shirts were also made in which the application of the techniques of joining by keys is missing. In the usual traditional shirts, the techniques of joining by keys are very rare. The terminal lines of the parts of the holiday shirts, as well, present various processing and decoration techniques applying the processing with «brezărău», the processing with crocheted lace.
