Flat cutting can't save the shortcomings of cheongsam

1, the figure is too concave and convex, and it is not enough to cut cheongsam.

2. Stretching can make the plane fabric close to the three-dimensional sense of human body, and the plasticity of the fabric also has a critical value, beyond which it cannot be fully achieved.

3. There will be obvious wrinkles in the concave-convex part and the part with large inclination angle under the armpit and arm.
