I claim the ornamental design for a garment, as shown and described.
The sole drawing FIGURE is a view of one side of a garment, showing my new design.
The jagged broken line segments represent portions of the boundary of the claimed design but are not part of the claimed design.
The remaining broken line segments, including those representing sleeves of the garment and the lower torso portion of the garment, are for illustrative purposes only and form no part of the claimed design.
The opposite side of the garment, not shown in the drawing figure, forms no part of the claimed design.
