“I say give a picture, at least you can send a very nice one and not risk them somehow getting a hold of a picture of the girl that is not flattering.”
I definitely agree with that, from the guys point of view I like to see a picture so I know there’s a possibility that she’s attractive. It doesn’t have to be a professional photo shoot, but it should give an idea of what she looks like. Also if your daughter has a facebook account make sure that she doesn’t have unflattering pictures of her on there, it’s amazing what people put up, even with good intentions.
