The article considers the variation in the style of clothing of the Alans populating the territory of the North Caucasus in 8^th – 13^th centuries. An analysis of pattern drawings allowed the author to assume that the style of Alan clothing was based on the essential pattern of the Oriental type with a soft line between the body and the sleeves. The analysis revealed that the pattern changed together with the variation of the sewing material used by the Alans of the North Caucasus from felt fabric with a certain width and length. As a result of research performed by the author, a series of issues remained unresolved. However, the article demonstrates a new direction of analysis of the style of sewn archaeological clothing, which can be used during the reconstruction of historical costumes.
