But there is no difference between how the large necklaces (she has chosen to wear) and the chokers sit on her neck.
Take a look. The only difference is the large necklaces cover more of the front of her neck.
"Collarbones to support those necklaces" have nothing to do with the necklaces she chooses.
"It's like she's forcing herself to look nice in those grand necklaces" is a suspicious comment imo. I rarely enter the fray in this way but I have to say it. Camilla is the wife of an heir, one day to be Queen. Her role demands a certain measure of grandness in dress. We all know enough about Camilla to guess that her preference is 'wellies' and kicking back in the country.
Camilla is not young. I think she knows that and is not attempting to appear anything but her age. Because she is older does not mean she cannot look grand, which she does when the occasion demands, and to good effect. She likely dresses the way good advisors recommend.
