The color yellow is often associated with summer. So how do you transition it to fall? By going with a little darker shade of yellow. Specifically, marigold. Marigold is a deep yellow, still bright enough to have all the wonderful traits of yellow but deep enough to be worn well into autumn. If you're wary of it, start off with a marigold bag like the one below.
