armholes

Armholes are openings through which the arm passes in garments, commonly referred to as armscyes in pattern making. They are cut into the bodice or other upper-body components and are shaped to follow the shoulder line and chest contour, providing space for movement without excessive looseness. The armhole shapes interact with sleeve construction; most woven garments use a set-in sleeve attached to a curved armhole, while raglan and dolman sleeves share the armhole edge with the neckline or extend from the shoulder. The depth and circumference of the armhole influence mobility, fit, and coverage. A high or deep armhole changes the amount of ease and can affect shoulder definition and underarm comfort; a low armhole offers more arm movement but can reveal undergarments or cause fabric strain.

In pattern making, the armhole is called the armscye and is drafted as a curve that starts at the side seam and wraps to the back, accounting for front and back shoulder slopes. Finishing methods for armholes vary: facing, bias-bound edges, binding, or turning the edge under; knit fabrics may use ribbing or bands to preserve stretch. Common fit issues include tight armholes causing restriction, gaping armscyes at the underarm, or excessive ease leading to sagging. Proper armhole design balances mobility, coverage, and aesthetics for the intended garment.
