Funny that this thread pops up today as I was contemplating this just yesterday and I disagree with JB's standpoint.
I was just thinking yesterday how even the most unconventionally attractive person can suddenly seem really attractive based on their facial expressions and the way they communicate with you. I was thinking this in a work meeting with three women, none of whom would turn your head in the street. But they were all really, really clever, accomplished, interesting women and the longer I was in their presence the more I was bowled over by their attractiveness. I also noticed things about each woman's appearance that made them attractive, but these were things you would have to observe for a bit to see the beauty in them (e.g. you might not look at them for five seconds and say 'wow, she's a stunner'). One had really amazing skin - very, very dark skinned black woman and her skin was so clear, it was beautiful. Another had amazing, twinkly blue eyes and a great laugh. I could instantly see why someone would find her irresistible.
Btw, I am straight, but was obviously having a bit of a 'lipstick-lezzer day' (as my lesbian mate would say!).
Most of us aren't gorgeous in a photo, but many of us are hot when you get to know us 
I know it can sound trite and corny, but beauty really isn't all about perfection and youth and conventional, male-led ideas of femininity.
