I'm a straight female and I always find this subject so damn interesting.
What women find sexy or beautiful in other women is usually different to how men think. I must say that most of the guys on this board seem to have better taste than average... I don't understand the fascination with girls that just look so plain and uninteresting. Anyway, my list of the most attractive women, IMO. A lot of them are models 'cos fashion's what I'm into.
I would add more but there is no time. Others are Adriana Lima, Monica Belucci, Alessandra A.
