I am about to win the promotional launch kit mask in an auction on ebay, and my family is wanting to help me create Corvo's Jacket by sowing it. Its the first time in a few years that I have wanted to get in costume for Halloween.

This is my first time doing this sort of thing, any and all advice is appreciated.

Things I really need help with are things like what materials I should use for his jacket, what should be the inlay, stuff like that.

Anyways like I said, this is my first time doing this, I really could use some pointers
