The ornamental design for the bottom garment with pick stitch, as shown and described.
FIG. 1 is a front view showing my new design for a bottom garment with pick stitch; and,
FIG. 2 is a rear view of the bottom garment with pick stitch.
The short broken lines on the surface of the bottom garment depict stitching and form part of the claimed design. The long and short broken lines depict the garment, the snap and reinforcing lines at the top and bottom of the loops, pockets, and seams and form no part of the claimed design. The surface of the material under the stitching also forms no part of the claimed design.
