One of the first items bought as a little aspiering goth was a pair of classic fishnet stockings. They costed a small fortune back in the days, but it was worth every penny. I did everything in them, and I mean EVERYTHING! We were the best of friends; laughing and planning for world domination. Then the bitch left me for a pair of PU pants..
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.
