Gentleman’s Riding Wear: “Habit de drap, Gilet de Piqué, Culotte de Casimir de Bombé.”
Since there are so few British fashion prints that depict men’s fashions, I often rely on French prints to see details of gentlemen’s dress. There are so many interesting details here: the pink-and-white striped cravat; the high shirt-points and ruffled shirt-front; the green gloves; the fobs at his waist; the striped breeches (difficult to see online but they are striped); the visible bootstraps; the spurs on his boots. Also note the chain or ribbon tucked in his waistcoat. Could that be attached to a hidden quizzing glass? With all the color and pattern going on here, this chap would no doubt have been dubbed a dandy in England.
In the caption, “Habit de Drap” indicates a wool suit. “Gilet de Piqué” indicates (I think) a quilted waistcoat. I have no idea what “Casimir Bombé” means in relation to breeches (“Culotte”).
The boots and spurs, along with the riding crop or carriage whip indicate that this is a costume for riding or driving.
