The inclination of men's suit is 15:1.3 in the front and middle side, which is about 5 degrees, which is 33.3% of the inclination from the chest to the anterior cervical fossa.

Take the 50% vertical front breast oblique line with the front chest width, see the chest line up 0.8 centimeters, move 0.8 centimeters as the floatation amount to the horizontal line of the front garment.

This floating volume is the length of the body's chest, which includes the amount needed to be included in the process design (chest cotton lining).

With the increase of the size, the floating amount of the front garment will also increase gradually.

The floating amount of the front garment can be determined through the calculation method of the front shoulder value B'/24 cm.

Such as B'-96 cm B'/24=4 cm, of which 2 centimeters for the front shoulder impulse, and 2 cm is the forward chest gate volume, its floating value is 0.8 centimeters.

If the front shoulder impulse is 4.5 centimeters, the floating value is 1 centimeters.
