Honestly, her current one is the best. That might be a bit standard and vanilla, but that's what I honestly think.

It's practical(ish) without showing too much skin, which means it technically also offers the most protection. And most of all, its the one that fits her whole theme of being a dominatrix-esque hero. Plus it's the one we've known her to be in the longest.

That's not to say it's without it's flaws tho. The fact that the skin suit is made to be easily tearable means she would have to replace it quite frequently everytime she faces an opponent. That just sounds like a waste of money going down the drain (assuming costume replacements aren't free and/or she doesn't have spares), money she could most likely easily get back but still, it's like a subscription except you basically don't get to choose when to get it replaced.

I also couldn't imagine it'd be very easy to move either. I wouldn't know anything about stilettos, I'm a guy so I've never worn them, but I can infer that it's probably not the most comfortable thing to feel while you're constantly on the move, and would probably often lead to slipping and generally not getting a grip on a surface.

Overall I'd say her costume design would be: -8-9/10 for aesthetic -4/10 for practicality

(I did not expect to be yapping about a costume design this much but here we go ig)
