If you are like me, you have been poring over all the new September issues or diving into all the fall trend reports that are littering the digital magazines. I like to take a moment to survey what's trending so that I have the lay of the land before going on a shopping spree. After all, research is key to any smart purchase. But now that I've taken a look at what's out there, I know I have already found a number of gorgeous fall clothes that I am coveting, and I have been shopping up a storm.

I just can't wait for the weather to change so I can start wearing all those fall things. The big question on my mind as fall approaches is, What are those key pieces that will update my current wardrobe so I look fashionable and on-trend without going out and scooping up a whole new wardrobe? Well, if you're in need of some style guidance, I'm here to help. If you swap in a few things, I know you will feel like you just walked out of a September issue. For me, these five things—clogs, dark denim, knit dresses, utility jackets, and plaid blazers—are doing the trick.
