That's how I feel, Emily, so at least I know I am not crazy! A few times I forgotten my lipstick at work and it drives me nuts. I have even gone so far as to go to a drugstore and buy lipgloss to get me through the day.
Shooting Star, I don't think my client's comment was meant to disparage my professional skills... most of the therapists dress business casual, a lot of them wear jeans with nice tops, and I am definitely not the only one to wear leggings. I think she commented because I usually am wearing a dress on the day she sees me.
