So based off the two pictures, I feel like I am bigger than my gf, despite us being the same height. (which I know for a fact) We actually have about the same body measurements more or less, But I always feel and see she has a tinier frame than me, which I believe plays a large part in why she passes and I don't, despite us looking similar and having very similar proportions. I'm on the left in the striped brown shirt, her on the right in blue:

(here I think I look noticeably bigger framed)

(but here I feel it's pretty much the same, just by lowering the camera...)

I always feel my head and waist are much larger compared to her to the point where it really gets in the way of being able to pass properly. However, upon measuring both, in inches we come out to the same size relatively, which is odd because it doesn't look that way. (much of my case might be my head shape being longer/bigger, not actual size around, since thats the same)
So I guess I'm looking for unbiased opinions. Am I huge or about the same size that it doesn't matter? I feel like my head in profile looks so awkward too....reads as very distinctly male and I worry even FFS couldn't help that. (even though, it seems maybe it could with forehead and jaw/chin reduction)
