Ha, I've never really been able to wear short lengths even in my teens, 20's, 30's or 40's. Enter 50 and nothing's changed. I still have that exaggerated overhang above my knee, varicose veins, and lots of big muscles. Not the most attractive in short skirts. Oh well! I Dow whatever I want regardless except at work where a slight amount of decorum is called for. (Slight!)
Oh, I definitely don't think 50 is old, even though my hair is turning grey.
