In addition to that little black dress in a girls closet there should be a little leather jacket. I've observed the leather jackets are already coming out in NYC. Such a versatile piece - like a great accessory (which I'm all about) it can change an outfit.
"Throw a leather jacket over a ballgown, throw it over a romper, throw it over anything and everything it's the quickest way to get that edgy, cool I didn't try too hard look." - Rachel Zoe (Oscars Episode)
Oh yes and for your feet you should always have a pair of red heels for that "pin up" feel and to add a splash of color!
