When do you wear a white bow tie?
Throughout the Early Modern period, western European male courtiers and aristocrats donned elaborate clothing at ceremonies and dinners: coats (often richly decorated), frilly and lacy shirts and breeches formed the backbone of their most formal attire. As the 18th century drew to a close, high society began adopting more austere clothing which drew inspiration from the dark hues and simpler designs adopted by country gentlemen. By the end of the 18th century, two forms of tail coat were in common use by upper-class men in Britain and continental Europe: the more formal dress coat (cut away horizontally at the front) and the less formal morning coat, which curved back from the front to the tails. From around 1815, a knee-length garment called the frock coat became increasingly popular and was eventually established, along with the morning coat, as smart daywear in Victorian England. The dress coat, meanwhile, became reserved for wear in the evening. The dandy Beau Brummell adopted a minimalistic approach to evening wear—a white waistcoat, dark blue tailcoat, black pantaloons and striped stockings. Although Brummell felt black an ugly colour for evening dress coats, it was adopted by other dandies, like Charles Baudelaire, and black and white had become the standard colours by the 1840s.
