Pantyhose is best in life

This looks like Kooh to me in Arin's outfit. That, or I've been playing too much Pangya.

I have a serious academic question, so if you would, please contribute an answer with the most pure intention. For the sake of science.

What's the difference between a pantyhose and stockings?

Stockings are thicker, I believe.

Stockings are more like socks. (two-piece)
Pantyhose are more like pants. (one-piece)

Pantyhose are like pants except thiner, nicer to skin, so they also cover the groin area(example post #23066 ).

Stockings are socks that go over the knee (as seen here post #22969 ).
