The ornamental design for a skirt, as shown and described.
The FIGURE is a front perspective view of a skirt showing my new design,
with the applique shown in partially opened position. The simulated
shoelace is _printed on the skirt. There is one seam which runs the length
of the skirt. The inside of this seam is partially _shown inside the
waistband. The rear of the skirt is identical to the front, except that it
is plain.
