That happens a lot. It only really bothers me if I'm particularly busy or talking to someone. I got used to it back when I made the decision to wear whatever I liked, which mostly consists of reenactment garb. Kilts are my go to modern attire. All we can do is try to look our best all the time. My sister-in-law saw me on her friend's facebook once. Seems that when I was out shopping one of the girls walking past took a cell phone picture and posted it. I didn't see the picture as I don't know the girl, but my sister-in-law assured me that I was well turned out.
