These look are casual cool and easy to incorporate into your own wardrobe. I bet some of these pieces are already in your closet!
Denim jeans are my favorite, paired with a classic striped tee, boots, scarf, along with a great bag and you have the perfect outfit. This can be worned from Fall through Spring with ease.
I love everything on this page not to mention Gwyneth, a classic beauty with a great sense of style. Some basic key pieces (a blazer, a great bag/clutch, ballet flats, and/or a statement piece of jewelry) can complete any look and take a plain pair of jeans to the next level.
Here's a great example of 10 key pieces. Wanna glam it up a bit! Adding a sequence top to a pair of jeans can do just that. How about adding some leopard shoes to your LBD.
