The classic fishnet pantyhose is a must in a goth girls wardrobe. Always start out with a classic pair, then add some with bigger nets as well.
if you get a hole in them, just transform them to German stockings (it's what me and my friends calls ripped stockings)
if you get a hole in the groin, just do as we all do: cut off the feets, put your head through the groin, in with the arms in the legs and the waist below your breasts. See, even (I assume: rich) Lady Gaga does it. I think goths do it better though..
AND - you are never bored with a pair of fishnets ;)
