MJ, here's the grey catsuit in BtAS (Batman, the Animated Series).

Also, in the Arkham City video game theres the option to change CW's costume to the BtAS version. Even better, this time her boots have heels 😊

Catwoman's been outfitted in a variety of catsuits (natch), leotards and dresses over the years, I think at least six versions in the comics before the iconic Julie Newmar TV version appeared. Off the top of my head I can think of black, grey, purple, white, orange, blue/red and green outfits, also several DPM ones. The evolution of Catwoman almost deserves its own thread. There's a page in one of the mid-60's comics that shows the various pre-TV show versions, I'll dig it out and post a pic.
Speaking of comics, in the BtAS comics there was a version of Catman, this time a guy so inspired by the grey Catwoman he committed burglaries costumed as her. Rather sadly he wasn't in the least passable as he was built like a brick outhouse. Needless to say, it didn't end well for him.
During the nineties the grey Bruce Timm Catwoman actually ran in parallel with the purple Jim Balent version. Leading of course to a dilemma...
Incidentally, my grey suit's made of 'inside-out' metallic latex for the semi-matte appearance. Only the front of the hood's shiny side out.
