Because Koreans and Chinese people's living habits and cultural backgrounds are the same, body shape is similar, body is not high, limbs are not too long, so shoulder is not wide. According to the characteristics of the body, the style can be used to avoid weaknesses. For example, Korean women are more full in their legs and breasts than those in northern China. In the structure, they can set up 1~2 centimeters in length, or split them into high waist segments. Because the hips are full, the shoulders can not be set too wide, so that the body will become slender. As the rear shoulder impulse becomes smaller, it is 0.7 to 1 centimeters, which will affect the widening of the armhole door. Therefore, the width of the cuff should also increase by 0.5 centimeters. The shape of the sleeve curve will be adjusted.
