So far I have the basic bodysuit sort of vaguely templated. My usual 10 piece bodysuit with lines all over it method 
I also have the jacket roughly shaped as well.
I was really debating whether to do her default ME3 outfit or the alternate, but the white and blue really does appeal oh so much 
Tomorrow I shall test my theory on making the hatched texture fabric work. I may have to resort to latex after all but would prefer something less grippy.
Also, the N7 armour in ME3 really looks like carbon fibre in resin At least the upper chest and shoulders.
