Used whenever an image containing an article of thin, tightly-fitting clothing (typically pantyhose or thighhighs, but not restricted to these alone) makes a point of highlighting the fabric-based nature of the clothing via one of the following methods:
An irregular, erratic line of reflective glossiness or sheen along the surface not due to folds, bunching, or creases of the fabric (or the skin underneath).
Thin, fine lines (that are not due to linear hatching or other fill techniques) where the fabric is stretched tighter against the skin and becomes slightly less opaque.
