During the fall, I wore tank tops underneath. When it got cold, I wore turtlenecks. Since the V-neck is deeper, I would put the crew neck in the front to enjoy the back style, wearing it as a 2-way. Size M Width: Approximately 57cm Reference Length: 119cm Crew neck side, length from neckline to hem: 111.5cm Soft V-neck side, length from neckline to hem: 100cm Sleeve (drop shoulder): 51cm This is a difficult garment to measure. Please forgive any errors.
