GLC- the first way you described is what my hands do.

I am going to try moving the hoods (it is cheaper!) but I may get some 40 cm. And yes my chest honestly is in the way of my arms but I don't know if it is enough to get wider bars. A woman helped me today (also fitted my bike), I would think she would have noticed the chest issue. I was a little too embarassed to say anything since a couple of the guys were hovering. I didn't want to go "So, do you think the fact that I am busty might be a reason to abandon the shoulder rule?"
