I need a new coat

After more than a month or so of dry weather, it has started raining today. Pouring, in fact. I went to buy my usual sandwich treat and had to get through torrential rain. And... And I was soaked, to there and back. Because I discovered that my cheap light coat/jacket, which I bought even cheaper on a sale at some cheap shop, about two years ago. I thought that with the hood, it would be suitable enough for rainy days. Mistake, big mistake. I had already discovered this coat was not much of a raincoat at all, but today I truly felt it. I might as well have been wearing a jacket made of sponge. So the moral of the story is: I need a new coat. If you have any suggestions, please feel free to tell me.
