The half sleeved sleeve type is a more close fitting sleeve, and the sleeve piece and the clothes body are divided at the bottom of the sleeve bottom door. The front chest width and the cuff width are all connected. If the angle of the front sleeve center line is set small, it is like extending the front chest width and the cuff width. When the arm is lowered, extra loose volume (bulging) is generated at the front chest width.

This is the reason why we set the angle of the half body sleeve center line larger.
