I've had both!
My mother is really fat. So a few years back I am cleaning the bathroom, focused on my work, and suddenly I startle thinking that I saw my mother... but it was only my reflection in the mirror that I caught in my peripheral vision.
These days, yes, I catch my reflection in a store window and think "holy crap, that's me!" It's good and bad. Good because I am healthier, and bad because ... well, I personally don't like being stared at by men, and it's happening more frequently again, even though I am over 50.
