Generally, the front trousers are free of pleat, and there is a province in the rear trousers, such as the type of trousers, or the horizontal section, such as sticking jeans.

(1) specification design

TL=0.6G+X

W=W*+ (3~4)

H=H*+ (4~6)

BR=TL/10+H/10+ (6~7)

SB=0.2H-2

FH=H/4, BH=FH; FW=W/4, BW=W/4+ provincial road; FSB=SB-1, BSB=SB+1.

(1) specification design

H=H*+20 (greater than 20)

BR=TL/10+H/10+10

SB=0.2H
