Cripes this is going to a tough one to do well.
The costume might not be too bad. A catsuit (OK, done one of those), with some strange knee and elbow pads (Hmm) plus a cloak. Not too bad so far. Found some different material too which will be lighter but is more the correct colour.
It's the extras - and how many to include. Belt, obviously. But sword?, Balisong?, knuckle dusters? (knuckle dusters!). Do we do the gun jackety holster thing? If so then guns, knife, and grenade are needed.
I need a lie down....
