here you get a detailed view of what i wear under my ballgown - my golden 5 inch stiletto heels and fishnet-stockings and a garter-belt. the fishnet-stockings have a very nice lace top and together with the high heels they create never ending long legs. on dancing-balls i prefer to wear stockings with a garter-belt instead of stay-ups. because only a garter belt manage to keep the stockings in place for a whole night where you dance and sweat.
it's the same with high heels - on such events i only wear high heels with an ankle strap.
