How did men’s fashion change during the Regency period?

Men’s fashion during the Regency era was still characterized by the three-piece ensemble from earlier centuries—a waistcoat, a type of pant, and a kind of coat—but it moved away from the embroidery, lace trim, and colorful fabrics of the 18th century. Men instead highlighted their well-cut pieces by choosing unadorned fabrics in darker, more muted colors. The waistcoat, or vest, was the only part of a man’s wardrobe that had some subdued flourishes. Moreover, by the end of the 18th century, men had stopped powdering their hair and started to wear it short and tousled, resembling Roman sculptures, and indeed the style was called à la Titus or Brutus.
