“Not only was he wearing the frilled shirt, the longtailed coat, the knee-breeches, and the silk stockings which constituted the fashionable attire of a gentleman bound for Almack’s; he carried a chapeau-bras under one arm, and one of his snuff boxes in his pocket.”
— False Colours by Georgette Heyer (1963)
Kit Fancot, the hero of False Colours, impersonates his older brother, Evelyn, Lord Denville, as a favor to his mama. He arrives at a fancy dress party held by the relatives of Denville’s betrothed. Unfortunately, he has no clear idea of what Miss Stavely looks like.
However, everyone at the party believes him to be Evelyn, particularly since he is dressed in his brother’s fashionable dress rig, starting with the frilled shirt. No, not the pirate shirt sported by a well-known comedian in the 1990s, but similar, I daresay:
The longtailed coat was designed to set a fine figure to advantage. The tails in the back were almost an afterthought, forgotten in the evolution of the formal coat from its original function–to separate when riding a horse . What was important was the fit over the shoulders, perhaps enhanced by padding discretely inserted in strategic areas. In the same way, the cutaway design revealed the upper thighs and slim (corseted, if necessary) waist of the gentleman.
Knee breeches were de rigueur if one expects to be admitted to Almack’s, and thus the standard for all fancy dress parties. They were critical for Kit to pass himself off as his brother, all while meeting the approval of the venerable Dowager Lady Stavely, (grandmama to Miss Stavely). Therefore, pantaloons worn on the street would be right out in such company.
Besides, the advantage of wearing knee breeches becomes immediately apparent when a well-formed man pairs them with white silk stockings. The little ties just below the knee, combined with the clinging material of the stockings, draw the eye to his shapely leg, the black slippers just the thing to command admiring attention when among one’s peers (and cross old ladies).
Kit carries a hat, a three-cornered affair called the chapeau-bras. The fellow pictured above has a two-cornered (bicorn) hat. Both collapse and can easily be kept in good order by the butler or other man-servant while the wearer enjoys the party.
Snuff-boxes are very personal items in the Regency. Snuff itself can come in a variety of flavors (I’m thinking of Miss Taverner’s Sort in Heyer’s Regency Buck). Heyer completes Kit’s disguise as his brother by having him take along, in his pocket, a recognized trinket of Lord Denville’s. Indeed, a snuff box conveys much about a man’s identity in the Regency–witness a Cyprian’s attempts to engage the affections of a dour, northern Scotsman through two years of ‘tedious’ courtship, her stamina continuously as she:
‘anticipated the grandeur of which his massy snuff-box and mode of living distinctly conveyed.’
