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 Old Bow and Chain Necklace, $22.99 A bold, fun necklace is a necessity in every accessory arsenal. And this gem from ModCloth would look equally amazing against a plain white tee and blazer or a LBD. The edgy and soft combo of the chain links and bow pendant work great together.
