It's my weight gain that makes me look more feminine. In my driver's license and passport pictures I look girly in the fat pictures and boyish in the skinny pictures. In all of those my hair was quite short. At the moment I have a sort of Velma Dinkley bob and I don't know what will happen if I keep that and lose weight.

But I do think that the places where men and women put on wrinkles and fat as they age are different, so unless someone is very very skinny you can generally tell. Although the manager in a store where I took a resume last month had me rather in awe -- she was heavy but small-breasted, and wore no makeup or jewelry and had very short cropped hair. I initially thought she was a man, and when I heard her voice I had a slight doubt, and when I heard her NAME I was still on the fence, until another employee specifically said 'she' when referring to her. :)
