You could try the V3/S3 tunic with a yellow/black texture, one of the facemasks with a black domino texture, and I'm sure there's some fitting Mary-Janes (shoes) around.
PhilC has or had a free cape on his page, that could work, too.
As for the age, maybe one of Thorne's facemorphs might work as well.
There's thousands of free daggers around as well, but I'm at a loss for the head cover, sorry.
