Suppose that a straight cloth strip is used as the collar first, and it is sewn together with the neckline of the garment piece. When the collar is turned over, it will be found that the neckline is tight because the collar is not open enough, revealing the back neckline. Taking the SNP point of the side neck point as the center and the size of 1/2 back collar arc length as the cutting point, the left and right sides were cut.

After cutting, the original tightly folded collar will naturally open outside the meeting, and its outer opening will be redrawn on the pattern when it becomes longer. It can be found that the outer opening of the collar has changed from the original straight line to the downward curved arc, thus resulting in the straight dimension X of the rear midline. The more cuts, the longer the outer opening line of the collar.

Under the same conditions, the collar seat is low, the back center line is long, the outer collar line is long, and the shape curvature is large; The collar seat is high, the back midline size is small, the outer neckline is short, and the shape curvature is small. From the appearance of wearing, the collar is high and straight; The collar is low and flat.
