Any fingering/sport weight yarn which produces gauge will work well. I used 3/2 perle cotton (about 18 wpi) in a stable gauge which does not sag or distort over time.

Worked in one piece from bottom up to armholes. Measurements included throughout instructions.

My original charted design.

This version includes a small jewel neckline. A Version B pattern is also available with a neckline 1/2” larger all around.
