The traditional shape of the knitted garment is generally straight, why?

The traditional modeling of knitted garments is generally straight for the reasons:

1, knitted fabric elasticity, drape better, seasonal soft to the body, in the woven fabrics need to be used to save the road, split, tucks and other means in order to produce a three-dimensional effect of knitted fabrics by the elasticity of the fabrics and drape to obtain, and thus the structure of the line can be simplified.

2, knitted underwear shape contour line and the inner structure of the line itself is not complex, do not need too much structural line, and at the same time due to the fabric's disintegration, crimping and other issues do not allow the use of too much structural line.
