Looks ARE subjective. What I find attractive, you may not deem so. Some people think anorexically thin size zero girls are more attractive. I do not, and find it disgraceful that it is such an issue in shidduchim today. Some people think a girl who wears a size 12 or 14 dress is overweight – Lucille Ball was that size, and she never looked overweight to me.
Some girls think guys who have facial hair are unattractive, others would find them less attractive without that facial hair. Some people like blue eyes and blonde hair, some think redheads are gorgeous, and others are turned off. It is ALL subjective. Why we are attracted to the look to which we are attracted, is a mystery that not even we can understand. We only know we are or are not attracted. And we cannot discount that mystery. It is why in my humble opinion NO MOTHER SHOULD SEE A PHOTO OF A GIRL before her son has met the girl. Her opinion of “attractive” should not be what determines whom he will meet. Neat, and presentable, trump someone else’s possibly flawed perception on looks, any day.
