A statement piece doesn't have to be a piece of jewelry, it can be as simple as a statement belt. They can inexpensively accessorize your outfit by just making a basic outfit look more put together.
Try adding a belt to a pair of pants, and a cropped or tucked in shirt.
You can add a cute statement necklace,or jewelry if you like but you don't have to! This makes an outfit special looking, without being expensive. You can also add a belt to the outside of the outfit. I would add gold tone simple jewelry to this one to bring the whole outfit together! 
The Bling Thing has so many cute belts for you to add to your collection to make accessorizing easy!
