On either side of UV, take points W and X on ij, with a horizontal distance of 5.5 to 6 cm between W and N, and a horizontal distance of 5.5 to 6 cm between X and O; draw a smooth arc connecting UWV and UXV, such that UWV∥xNy and xOy∥UXV; UXV is the front underarm body seam, and UWV is the back underarm body seam.

[0059] The arc smoothly connects S2P and SQ;

[0060] The back piece is qmowRLsq, the back underarm piece is RUWVsMR; the front underarm piece is US2PEVXU, and the front piece is SAFHdEQS;

[0061] As attached Figure 3 As shown, the deformation of the front garment piece in step 4 of the present invention is specifically as follows:

[0063] The front waist dart and the deformed front body piece make the finished garment fit tightly to the chest without lifting up when worn, and the front and back are balanced. The front and back waist darts make the finished garment have a strong three-dimensional effect when worn, reflecting the beauty of female lines.
