(Almost wrote 'on Mary's part' 
her perfect posture does remind me of Crown Princess Mary of Denmark).
Becoming more British? Hard to say, of course, She is an amiable and well-mannered woman so her behavior is on-point always. But the pressure on her for a lot of reasons must be enormous still (and all the criticism must be hard to absorb). Rather than lessening I could see it increasing as the newness dies down and reality sinks in. Not that the reality is 'bad' just must be hard, I think. Just my hunch.
I love Mary so much. I wonder if Meghan's posture is from her work as an actress.Excellent posture on Meghan's part.
She is 'full-body' into her 'role'. Also all that yoga gives her elegant body awareness. We will never see her slouching in her seat. It's not necessarily a bad thing though I do think Meghan is under a lot of strain these days. She for sure handles it well overall.I would say yes.
I mentioned the subdued energy (someone else saw tenseness, I did not). It comes across in the video, not in the still photos. JMO. In general there is just less 'overtness' in her manner and that makes sense for a whole raft of reasons: most important being 'conservation of energy'.
