I think the reason I never felt the pressure of women's appearances/sizes was because my main friends as a child were boys. My brother was the main person I hang with. We played with mainly boyish things like toy cars and we had fights where the winner was somehow considered intrinsically better simply for their superior physical strength.
So considering my main influence was of boy-things, I considered "strength" and being "macho" more important than fulfilling a certain standard of appearances. Of course as I grew older I became more feminine (mainly because of my primitive family's sexist gender expectations where I was forced to wear skirts and stay at home, cook, clean, and look after the younger children while my brothers were out playing sports and encouraged to be "men"), but becoming more "feminine" didn't increase the social pressure that most other girls seemed to have because I already had a different culture with different set of standards ingrained in me.
