(19th century) wearing dress coat with
top hat for
white tie. A
dress coat, sometimes called a
swallow-tail or
claw-hammer coat, is the coat that has, since the 1850s, come to be worn only in the evening by men as part of the
white tie dress code, also known as evening
full dress, for
formal evening occasions. It is commonly referred to as just a
tailcoat in America, or
tails in Great Britain, but amongst tailors (both British and American) and
dress historians it is traditionally called a
dress coat to differentiate it from other types of tailcoats. The modern dress coat is an evolution of the coat that was once both day and evening dress. It became increasingly popular from around the late 1790s and was particularly widespread during the
British Regency, and in America in the 1830s to 1850s. The dress coat was supplanted in the 1840s as formal day wear by the frock coat, which was in turn replaced in the early twentieth century by the
morning coat. In the Regency period, the dress coat with gilt buttons was always worn with non-matching trousers, pantaloons or breeches. Since the Victorian era, the modern dress coat for evening wear has been worn with matching trousers of the same cloth with two stripes of braiding down the side. The resulting suit is traditionally referred to by tailors as a
dress suit. A dress coat is waist length in the front and sides, and has two long tails reaching to the knees in back. Sometimes there is a pocket on the inside to hold
gloves. Since around the 1840s the dress coat has lacked outside side pockets, but prior to this it took flapped side pockets. Since the early twentieth century, it has become acceptable in America to have a welted pocket on the outside of the chest to hold a pocket square, but prior to this dress coats lacked any outer pockets. The front of the skirt is squarely cut away. Since around the 1830s the coat has been constructed with a waist seam that allows greater waist suppression. From the
Victorian era, the
revers has taken facings in silk (
grosgrain or
satin) on the
lapels. Although it is double-breasted, since the 1870s, the dress coat no longer fastens in the front. As a result, although there are two rows of buttons, these are all non-functional, serving only a decorative function. As part of modern
white tie, a black dress coat is worn with a stiff, white wing-collar
dress shirt, with a plain starched (pique or plain-weave) bib that takes shirt studs,
single cuffs fastened with
cufflinks (of a white metal); a matching white marcella cotton or satin silk bowtie and white
waistcoat; black trousers with one or two silk galon; and black oxfords (without a toe cap) or
pumps; the shoes must be polished to a mirror shine or be made of
patent leather and are worn with black, over-the-calf silk socks. Additionally, a top hat, silk dress scarf, and white dress gloves are either seen as acceptable or mandatory. A gentleman's top hat was traditionally made of silk plush, although the last supplies of this material have now been exhausted, so inferior hats are made of silk or felt cloth. ==Morning coat==
