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 line shading or other fill techniques) where the fabric is stretched tighter against the skin and becomes slightly less opaque.
* Some combination of the two.
