When turning 40, the question is "What to wear". Keeping it classy and never trashy is a motto to run by. A few key pieces to have in your closet is a great pair of heels and a designer purse. Having these key objects can always be considered your staple items. Adding in a great black skirt and a striking pair of jeans is yet another way to keep things flowing. Adding in a great leather jacket is just a plus to success to style yourself for the 40's club.
