Mrs Bennet begins to raves about the elegance of the Bingley sisters dresses before Mr Bennet cuts her short. Correct me if I'm wrong but JA hardly describes costumes. I think part of her art of writing was to describe personality quirks, gestures, qualities, accomplishments- or lack of. She only occasionally describes what a charecter looks like. Perhaps it was not good manners for a Nineteenth century novelist to describe clothes?... I must say from the text quote about Mr Hurst as 'a man of more fashion than fortune' I also had the impression of a dandy.
