Most ladies don't like to go spend a wad of money on styling an outfit you likely will never wear again. I have to admit I have done this a few times: It's called the "Princess Diana" syndrome: wear it once and get rid of it!
A great diversion is to shop your own closet! This is a great way to save some dollars to spend on others instead of yourself.
Chances are you already have what you need to inspire a smashing look. I'm sure just about every female closet has a little black dress, and a pair of gorgeous heels. These items are great foundation pieces to create the rest of your look around.
