I have to echo what everyone else here is saying about your hip to waist ratio. I think a lot of cisgirls would be jealous of you with a figure like that.

But you know, transition is just one of those things where the process is different for everyone. The amount of time it takes, the amount of work you have to put into it, and where you end up when you've gone as far as you can, depend so much on the individual. Believing that you are not getting anywhere just because a year of HRT didn't get you there by itself is really the wrong way to look at things. As others has said, being read as female has just as much to do with the way you present yourself as your actual body. Even if you have a pretty feminine figure, if you still dress like a boy, talk like a boy, act like a boy, etc., people will still probably see you as a boy. If you think about it, some FTMs are able to pass as male just by cutting their hair, binding their chest, and dressing in male clothes. It only makes sense that you might not necessarily come across as being female if you can't take those kind of things into account. Physical development takes time, and at your age I think it's safe to assume you are far from finished. Not everyone is busting out of their bra after only a few months of HRT. I'm still not even quite a B cup, even after two and a half years of low to moderate dose HRT and three months of full dose HRT. And based on my genetics, well lets just say I may have some more developing to do.

But looking at
this picture of you in particular, I would say you are definitely at the point where you should be able to pass, if all the other pieces were in place. I know you're not being allowed to present as female as home, which I'm sure is really frustrating. But I really think that once you are able to move out and adapt a more female presentation, you should be passing in no time. In the mean time, just let the hormones do their thing, and I think you'll find that things really only get better as you give hormones time to work.
