I don't know if you are a man or a woman. First of all, you should feel that black stockings are thinner. You can fully show your beautiful legs. Black stockings are thinner, because in color theory, black feels tighter than light color. For example, a person's legs are not very thin, but wearing black pants will be a little thinner. High heels are a beauty's favorite. Not only temperament, but also slender legs (visual feeling). So as to look in good condition. It is said that when men look at women, they look at their bodies first, and if they are spicy, they look at them second (hearsay, hehe). So men think black stockings and high heels are sexier.
