Suits and sneakers don't mix once you get past a certain age, and neither do skirts and athletic shoes. Have you ever seen those women downtown, briskly walking in skirts and tennis shoes on their lunch break?

The only thing missing is a shopping cart loaded down with all of your worldly possessions.
