The most common way (and also the most erotic) is to wear a suspender belt that goes around the waist and drops extensions that are clipped to the tops of the stockings.   Hold ups, where the top of the stockings has an added band of highly sticky but elastic material that stops the stocking sliding down your thigh.  For the summer a good alternative to a full stocking is a knee-high stocking.

The most convenient - and presently fashionable - way to wear stockings is to wear briefs over the stockings and garters. If the briefs are reasonably full, this pins the garters to the body, which makes it less obvious exactly what is being worn.

Choose from standard stockings or go for the currently fashionable patterned stockings and opaque stockings.
