Third cosplay I made myself (except for sewing the fur onto the jacket; that was my mother). Basically, this one has been having on/off alterations for quite some time, and I'm somewhat debating on whether I want to make the actual Manga version as well (A much longer coat).

Materials for the jacket:
Black cotton fabric
interfacing (in black)
one black, 60" zipper
Faux fur (a brown and black mixture)

Materials for the knife:
One pocket knife
Plastic (I used left over house siding from a remodel, as in the stuff that goes on houses exteriors)
Black spray paint
Recommended that you have a screwdriver with you, to remove the blade from the pocket knife, and also have a marker or pen or SOMETHING to draw the outline of the blade onto the plastic. Also recommended, for Convention Safety, to sand the edges of the plastic down so that no injury can be done.

Wig from Ebay, with a LOT of styling (used Got2B products, along with hair clay).

Regular black pants, boots from a thrift store (DAV).
