Looks are VERY important in a marriage and should not be diminished by ignorant statements of its pure personality. If a husband does not find a wife attractive, you have tzores!
On that note, I also disagree with resume’s and pictures. Seeing the person in real life, you get to see her and her personality. Sometimes her personality is so beautiful it increases her overall attractiveness.
However, from the perspective of a boy who lives far away from a girl, I can see the value of a picture. For example, if a girl has black hair, and the boy (yes, his preference and mishugas) is he only dates blonds, why would he fly to see someone who is not his type; regardless of the personality.
But this has nothing to do with MO, yeshivish or chassidish. the importance of looks are vital and their are countless stories of the sad outcome one one ignores it.
