Günther F. Hertzer, Garment cutting in the twentieth century (1892)
“ We also find forms which are very erect or straight in the back but throw their arms forward, and do require the armholes forward from the normal position. Now, no matter if the form is erect or stooping, the armholes do not require to be larger or smaller. Because a man throws his arms forward or backward does not show that his arm becomes larger or smaller. If the armhole is required to be cut 1⁄2 an inch more forward the back should be that much wider. If the armhole is cut 1⁄2 an inch backward the back becomes 1⁄2 an inch smaller—the location of the armhole changes, not the armhole. ”
