One thing to keep in mind is that your level of exertion has a lot to do with how warm you are. So you'll want to dress warmer for a long run than you will for a race or a tempo run. For interval days, you'll want something with a zipper that you can open before your repeats and close so that you don't get chilled during the intervals. And so on.
