Can one-piece flat-cut cheongsam not be pulled back?

One-piece flat-cut cheongsam can't be pulled out. Because the siamesed flat-cut cheongsam is not cut with the chest and waist provinces to achieve the fit effect like the western-style improved cheongsam, the siamesed flat-cut cheongsam needs to be pushed and pulled when it is cut, while the siamesed flat-cut cheongsam only has two lines sewn on the front and back sides, especially the curve of the chest, waist and buttocks, which is the key part to shape the body, and the pushing, returning and pulling are concentrated in this part.
