FIG. 1 is a first perspective view of a garment showing my design;
FIG. 2 is a front view thereof; and,

The long-and-short broken lines along with the left and right outer solid line perimeter edges of the garment define the bounds of the claim. The long-and-short broken lines are not claimed. The areas and even-length broken lines outside of the shaded and solid line parts of the garment depict portions of the garment that form no part of the claimed design.
