I claim the ornamental design for a neckwear, as shown and described.
FIG. 1 is a perspective view of a neckwear, showing my new design;
FIG. 2 is an enlarged perspective view thereof;
FIG. 3 is a front elevational view of FIG. 2;
FIG. 4 is a rear elevational view of FIG. 2;
FIG. 5 is a left-side elevational view of FIG. 2;
FIG. 6 is a right-side elevational view of FIG. 2;
FIG. 7 is a top plan view of FIG. 2; and,
FIG. 8 is a bottom plan view of FIG. 2.
The broken lines showing a person wearing a shirt in FIG. 1 and a neck strap in the figures depict environmental matter and form no part of the claimed design. The remaining broken lines represent stitching, and are part of the claimed design.
