When I was just out of seminary, a mother of boys in shidduchim asked to see a picture of my sem class. She pointed to one particular girl, who happened to be a very organized girl with great middos, and said, “This one would probably be good for my ‘Yitzy’, but she has a bit of a double chin.” I told her that it was just that picture, and that really the girl was thin, but she wouldn’t listen.
One look at one picture was all it took for her to eliminate a wonderful girl!
