a fun twist on the sci-fi character in a tight bodysuit look is if they're a cyborg/robot and that isn't a bodysuit, that's just their body
also got a thing of mystery and trans-human flexing about it if people think you're dressed slutty but you're actually completely naked
I feel like an important part of making transhuman characters is giving them features where a normal human trying to do normal human things with them will be baffled/shocked by some part of them whether that's "Boots? No, those are my legs, they don't come off. Well they do, but at the hip," or causing a sting of concern and panic when they take hot stuff out of the oven bare handed.
