My purse?
Two pairs of glasses. At any point in time I'll be wearing reading glasses, distant vision glasses, or distant vision sunglasses, all prescription, so two of those are always in my purse.
Lipstick and/or lip balm, powder, a comb, pencil eyeliner, eye brow highlighter, nail clipper, and nail file, all for touch ups if needed.
Checkbook, wallet (with credit cards, insurance cards, id cards, cash, change), pen, and corporate ID badge for when I have to go to the main office campus.
House keys, car keys (when not in the car), cell phone, and cell phone charger.
Yes I carry a lot. 🙂 And I love it. I am so much better organized with my purse than a guy trying to keep things in pockets!
