Check out these beauties. They are under US$50 and available right now from the Gap. I love a bargain! Not to mention, they are bound to go on sale within a month or two, if you are willing to wait.
The ballet flats are available in gunmetal, gold and black and the wedges have the following color options: plum, brown and a dark denim.
And at those prices and with such good looks, totally worth Fall-ing for! *Ahem*
