I don't think there is much mystery to it. Usually it is obvious what attracts me
The question is more: Was it something concrete, on a list, that you seek out? Like "tall, blonde, skinny, speaks French, likes Mediterranen food, has office job" Or is it something more ephemeral that sends shivers down your spine? And -- here's the thing -- can a woman have that shivery-something and beat out someone who is theoretically more your "official type"?
