Help with Halloween costumes for this weekend ASAP! (=?

I'd say the Midnight Dark Angel would be the easiest to do on short notice. Just wear any black skirt, ripped black tights and a sparkly top. Then all you would need would be dark intricate makeup, trust me its really easy to do so don't worry. :D For the wings what I did was get a hanger, bend it into the shape you want and pull tights over them, in any color (i used pink and black, it was cool :D) then just tie the two wings together with black ribbon and make shoulder things to keep them on. You can get black ribbon anywhere so yay!! I hope this was useful to you :P
