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.
