My new project?

I am probably certifiable, but I am going to try and make a jacket based on this for a part in a halloween costume (I'll make the whole costume as pictured, with a slightly different jacket). My idea being to make it black + off-white, with trim around all the seams and a design on the front bottom openings and around the neckline and on the sleeves, instead of everywhere. Probably a more tailored and fuller cut too, because I like those. Wish me luck; if I succeed it should be totally awesome.
