In this study, mechanical properties of the fabrics were investigated in order to find the cause for seam puckering problem in armhole and neckline area of woman’s blouse. The same model of woman’s blouse was produced from two types of fabrics with different raw material content: 100% silk and polyester 100%. The obtained results show that both fabrics have a low shear rigidity, which indicates that fabrics extension in bias direction is high. The fabrics extension in bias direction has influence on seam puckering in armhole and neckline area of the blouse because there is sewing in bias direction except sewing in warp and weft directions.
