Some terrific pictures there, Vermis. There is sense in using a circus outfit as the basis, given that Superman wore Eugene Sandow's clothes with an added cape, but the fencers just look so stylish. They also fit the design philosophy behind Darwyn Cooke's redesign of Catwoman's suit, which, in his and Cameron Stewart's hands, looked liked soft leather, intended to provide some protection against knocks. Later artists decided to make it look like spray-on latex instead. The goggles were supposed to have night-vision lenses. Unless those are available in Victorian times, why would your ladycat wear them? Perhaps she climbs down chimneys and needs to keep the soot out of her eyes - in which case, she'd have to be small and light, not some strapping amazon.
Strapping amazons are another subject altogether!
