Basic technical jacket block - measurements
      This block eliminates shoulder and armhole seams while maintaining arm 
        lift. This ´shell´ provides a basis for many variations in yoke 
        lines and the degree of arm lift, and elbow articulation, can be varied 
        according to the posture of the intended end use. The block is close fitting 
        and appropriate for two or three layer shell garments.
