The present invention provides a bottom garment that can provide high wearing comfort and also can effectively prevent the occurrence of out-of-shape wearing at leg edge parts. The bottom garment includes: a back section (12 (back body member 102)) adapted to cover buttocks of a wearer; a front section (11 (front body member 101)) facing the back section; and a crotch section (103). Right and left end edges of the front section (11) are connected to right and left end edges of the back section (12), respectively. A front end of the crotch section (103) is connected to a lower end of the front section (11). Aback end of the crotch section (103) is connected to a lower end of the back section (12). In a pattern diagram, the back end of the crotch section (103) protrudes so as to form a V-shape having a protruding central portion and a gradually increasing width toward right and left end edges, the lower end of the back section (12) to be connected with the back end of the crotch section (103) is recessed so as to form a V-shaped notch, and an angle (±) of the V-shape is greater than an angle (²) of the notch.
