Well thats the tricky bit. It took me a while to work it out and I still don't think I'm right.
But she's essentially got rubber/pvc/leather trousers on that go up over her hips. (in one of Mark H's drawings he's written that they're leather but he always seems to paint them like they're rubber or PVC) Over them are black stockings and suspenders. On her hips she has the holster/belt thing that also attaches to the cod/lady piece (?) which lies OVER the suspenders. Then there's the bodice which stretches down from her ears (she has some kind of translation device/thing over each ear ), fastens to make the collar, then continues all the way down to just below her navel where there's two press studs fastening it to either the belt, trousers or the codpiece thing. At the back its shortened to just over the suspender belt.
That's what I think anyway. I know its probably a bit in depth but I needed to try and work it out so I could build it.

I'm just working my way down ... And keks! I thought that was just a Scouse phrase! Not heard that for years.
