Chiming in my agreement here for Draco and the gray on gray! But also, I think the thought that Snape would wear the belted coat is a good one. I don't really see him wearing cropped trousers though - I think that he'd actually sneer or look down upon people wearing those. I also think that he wouldn't wear them because after lanky teen years, a person really learns how to dress for their body type (at least sometimes) and I think he'd have the knowledge and means to make sure all of his clothes were perfectly tailored.
