There were very few beauties, and such as there were were not very handsome. Miss Iremonger did not look well, and Mrs. Blount was the only one much admired. She appeared exactly as she did in September, with the same broad face, diamond bandeau, white shoes, pink husband, and fat neck.
This is from Jane Austen's letter to her sister Cassandra. I wonder what does "pink" mean in this context. Does it mean Mrs. Blount's husband has a pink face or is there any kind of metaphor to it?
