Preparations

I am currently speculating and preparing how to approach this cosplay.
Hrist Valkyrie's armour is something to be reckoned with, and after my most recent cosplay as Rose from The Legend of Dragoon (the standard outfit) I know it's going to be a real challenge. However, if I can find a good method of putting it all together then it should make things a bit easier.

I'm not sure about what to do for the halberd yet, but I have an idea if I can just find what I want.
My current ideas for the drape are to probably by a long white skirt (although I hate the damn things) and cut the slits in it before putting the decoration on. I can probably use the black wig I used for Rose, and the rest is mainly armour (plus a sword of which I can just buy a wooden one on eBay I should think).
