As we follow Anne around to different places, we are also watching a progression of lifestyles and manners. We start with the elegant and lavish Kellynch, and the formality of Sir Walter and Elizabeth.
On to Uppercross, where the Musgroves live in a good style, but not as formal, and definitely old-fashioned. Their daughters are importing the latest styles, though, and becoming more elegant and fashionable. Charles and Mary have less money but more elegance than his parents. The cottage is in the latest style (there was a cottage craze at the time), and although they don't have a carriage, Charles has a curricle, which is a small, light open vehicle, very stylish at the time. They have breakfast later than the Musgroves too, which is an upper class thing to do. The manners at Uppercross are more relaxed, casual and open, and very inclusive. No one can manage to do anything without involve everyone else.
At Lyme we see the end of the scale. The Harvilles are not well off, and live in a small, crowded house. Their manners are simpler, warm, open and friendly, very willing to include Wentworth's friends. Anne finds them delightful.
How does Anne behave in these different environments? She fits in, while remaining herself, with her low-key very good manners, the moving backdrop behind her highlighting her quiet, gentle personality.
I'm not an expert on details of fashionable life in 1814, but the annotated book I have is full of such things, and although the overall picture is clear enough anyway, it adds some richness to learn more about the background.
