I decided to start a new feature on the blog: Fly Finds of the Week.These are pieces that add instant flair to your existing wardrobe. And best yet? Everything's affordable. I'll offer four picks every week at different price points {under $25, $25-$50, $50-$75 and $100 and under}.If you're in the market for a new "it" piece, look no further. You don't need to drop a load of cash to update your wardrobe. Just adding one of these pieces is enough. Below are four of my favorite items under $100.

The edgy and soft combo of the chain links and bow pendant work great together.Click more to see the rest of the Fly Finds of the Week.
