Man: Long green Redingote, or overcoat, in the English style.  Long brown trousers, striped waistcoat or vest, top hat, gloves and boots. Fashion Plate via Journal des Dames et des Modes, or Costume Parisien. Definition Redingote Or Coat Or Pelisse: Long fitted outdoor coat worn over other garments for warmth. French word developed from English words, riding coat. French fashion plates call these coats a Redingote and English plates call them a Pelisse, Or Walking Dress, or Carriage Costume. These are the types of outfits worn by Jane Austen and contemporaries in English magazines, where French fashions were obsessively copied despite the two countries being at war for many years.

This same Fashion Plate is seen below for the gentleman.
