Make summer last a little longer

Is there a summer dress that you really want to keep on wearing but the weather is not allowing it? But how cold is it? It depends on where you are but if it is not coat weather yet I have a quick fix. Just put on your dress and on top of it a sweatshirt and problem solved!
