A Visual Guide to 19th Century Menswear. Men’s fashion changed very little during the nineteenth century, especially when compared to women’s fashion of the same period. For this reason, I thought it better to provide a general overview of the century, looking at changes decade-by-decade as opposed to year-by-year. In this manner, you can see the slow evolution of nineteenth century menswear, from the Regency dandyism of Beau Brummell to the matched three-piece suits of the late Victorian era. Changes were subtle, but significant, each of them moving men’s fashion one step closer to the elegant silhouettes still evidenced in fashionable menswear of today.
