HEELS!
You can reexamine the theory of wants vs. need, but for a girl heels will always be placed in the "need" category. You can never have enough pumps. Whether you're splurging on YSLs and Louboutins, or indulging in the next best thing at Charlotte Russe...you know you HAVE to have those shoes. The relationship between a girl and her heels is a beautiful thing. Almost as cute as a boy and his sneakers...almost.
Try not to fall in love. :)
