reclothing herself with manner and style

What do you mean by manner and style here? Manner is a method different from "manners= courtesy= etiquette", does it sometimes mean "courtesy"? And what does style mean here? An elegance?

"It's too bad you are not going East," she said, reclothing herself with manner and style. "But you must go on to Leavenworth, I suppose?"

"Yes," said Easton, "I must go on to Leavenworth."

I only want to know what manner here means. The only meaning I know is method or way.
