The purpose of the present invention is to provide a bottom wear capable of suppressing a situation in which an underwear worn by a wearer is slid in a wearer's stature direction with respect to the wearer's waist portion. The means for achieving the purpose is a bottom wear including a waist-encircling section, whereina cylindrical part including a cloth of bottom wear and a planar material different from the cloth, or a cylindrical part including a planar material different from the cloth of bottom wear is present at a back portion of the waist-encircling section and inside the bottom wear,the cylindrical part is disposed in such a manner that the axis direction of the cylindrical part is substantially parallel to the waist-encircling direction of the waist-encircling section,the static friction coefficient of the inner surface of a rear portion of the cylindrical part is 0.2 or more and 1.0 or less, andthe stress of a front portion of the cylindrical part at 10% elongation in the transverse direction of the cylindrical part is 10 N/25 mm or less.
