The uniform is that of a Heavy Dragoon Guards officer of the 1840s. It has a skirted red coat with Garter blue velvet cuffs and facings embroidered with the Tudor royal badge of the Portcullis. Helmets with white swan feather plumes are worn when on duty, even in church. Officers wear gold aiguillettes and carry sticks of office which they receive from the Sovereign on appointment. Cavalry swords are worn, and long ceremonial battle-axes, over 300 years old, are carried by all the Gentlemen.

Women's fashion

.
Women's clothing styles remained confining and cumbersome for most of the period. The hoop-skirts of the 1740s were left behind, but wide panniers (holding the skirts out at the side) came into style several times, and the aesthetic of a narrow inverted conical corseted torso above full skirts prevailed during most of the period.
In the 1780s, panniers finally disappeared, and bustle pads (bum-pads or hip-pads) were worn for a time.
By 1790, skirts were still somewhat full, but they were no longer obviously pushed out in any particular direction (though a slight bustle might still be worn). The "pouter-pigeon" front came into style (many layers of cloth pinned over the bodice), but in other respects women's fashions were starting to be simplified by influences from Englishwomen's country outdoors wear (thus the "redingote" was the French pronunciation of an English "riding coat"), and from neo-classicism. By 1795, waistlines were somewhat raised, preparing the way for the development of the empire silhouette and unabashed neo-classicism of late 1790s fashions.
Gainsborough's 1785 portrait of Mrs Hallett (right) captures the exact transition between the tight bodice and elbow-length, ruffled sleeves of the mid-18th century and the natural waist and long sleeves typical of the 1790s.

GownsThe usual fashion of the years 1750-1780 was a low-necked gown (usually called in French a robe), worn over a petticoat. If the bodice of the gown was open in front, the opening was filled in with a decorative stomacher, pinned to the gown over the laces or to the corset beneath.
Tight elbow-length sleeves were trimmed with frills or ruffles, and separate under-ruffles called engageantes of lace or fine linen were tacked to the smock or chemise sleeves. The neckline was trimmed with a fabric or lace ruffle, or a neckerchief called a fichu could be tucked into the low neckline.
The robe à la française featured back pleats hanging loosely from the neckline. A fitted lining or under-bodice held the front of the gown closely to the figure.
The robe à l'anglaise featured back pleats sewn in place to fit closely to the body, and then release into the skirt which would be draped in various ways.

Jackets and redingotes

Toward the 1770s, an informal alternative to the gown was a costume of a jacket and petticoat, based on working class fashion but executed in finer fabrics with a tighter fit.
The Brunswick gown was two-piece costume of German origin consisting of a hip-length jacket with "split sleeves" (flounced elbow-length sleeves and long, tight lower sleeves) and a hood, worn with a matching petticoat. It was popular for traveling.
The caraco was a jacket-like bodice worn with a petticoat, with elbow-length sleeves. By the 1790s, caracos had full-length, tight sleeves.
As in previous periods, the traditional riding habit consisted of a tailored jacket like a man's coat, worn with a high-necked shirt, a waistcoat, a petticoat, and a hat. Alternatively, the jacket and a false waistcoat-front might be a made as a single garment, and later in the period a simpler riding jacket and petticoat (without waistcoat) could be worn.
Another alternative to the traditional habit was a coat-dress call a Joseph or riding coat (borrowed in French as redingote), usually of unadorned or simply trimmed woolen fabric, with full-length, tight sleeves and a broad collar with lapels or revers. The redingote was later worn as an overcoat with the light-weight chemise dress.
