Sometimes in the fall in my city it rains...so you may need a rain jacket...

 Oh, sorry, what I meant to say was, sometimes in the fall it is imporant to purchase a large FUR jacket, because they are apparently SUPER cosy when it rains outside, and are able to repell water like no other.  I mean, the polar bears do it right??? Oh no wait, they live in the ARCTIC, not in one of the most mild, damp, rainy places on the planet..enough with the fur already folks. It's only October!
