PROBLEM TO BE SOLVED: To provide bottoms with L-shaped pocket the waist size of which is flexibly stretchable while keeping the bottoms look nice/beautiful without spoiling mass productivity. SOLUTION: The bottoms with L-shaped pocket are structured as follows: a rubber tape 60 and one end of a stretch-preventive material 61 are diagonally sewn up on the end part of an extending portion 53B with diagonal stitches 60a so that the upper ends tilt toward the side of a housing portion 53A; the length of the flexibly stretchable part of the rubber tape 60 corresponds to the lengthαbetween the upper end of stitches 60b for sewing the other end of the rubber tape 60 and an intermediate position of the stretch-preventive material 61 onto an adhesive fabric lining 50, and the upper end of the diagonal stitches 60a at the upper end of the tape, and corresponds to the lengthβbetween the lower end of the stitches 60b and the lower end of the diagonal stitches 60a at the lower end of the tape. The lower end of the rubber tape 60 stretches longer than the upper end of the rubber tape 60 when the extending portion 53B moves in a direction of being pulled out from the housing portion 53A because the lengthβis longer than the lengthα, and thus the extending portion 53B rises in a direction indicated by an arrow, when the extending portion 53B is pulled out from the housing portion 53A.
