On goth ninja:
a) I like it when girls dress goth ninja. My wife does it accidentally occasionally (she likes layered loose cardigans and monochrome). Guys, not so much.
b) This looks awesome (from your link):
c) And this is pretty cool too:
(that they have gothninja Tintin...not a fan of the gothninja pant/shorts with black socks thing)
d) Ninja/nun needs to be a look
