1816  Blue Riding Habit, French. High-waisted blue riding dress with a train, the long full skirt being necessary to cover a lady’s legs and preserve her modesty when riding side saddle. These riding habits were usually designed by men and were in two pieces, a jacket and a skirt, worn over a shirt. A military style bodice decoration, high pointed collar and a knotted pink dotted cravat worn underneath that imitate male styles, or even Dandy fashion. Sleeves are very long as was the trend in French riding habits. Yellow gloves and a masculine style beaver hat. This print was designed by Horace Vernet and engraved by Pierre Baquoy. Fashion Plate  via Journal des Dames et des Modes, or Costume Parisien. Although, there are very similar riding habit fashion plates in other magazines.

The type of outfit Jane Austen and her friends would have worn if they went horse riding. https://books2read.com/SuziLoveFashionWomen1815-1819
