Here's a quick snapshot of the outfit underneath the cloak. I based it on the outfit Vin is wearing on the cover of the second Mistborn novel, The Well of Ascension.
Check it out, I found another Mistborn at Comic-Con! I dig her giant koloss sword. I think I need to make my own.
I tried to steal a giant warhammer from a guy I found the same day at the con but he only let me borrow it for a quick (blurry) pic. Apparently this was made by some guys in Canada who make awesome LARP weapons.
BTW, I got a picture of myself with Brandon Sanderson! More on that next week.
