This elegant top hat will add timeless style to any outfit. Constructed of 100-percent wool felt, this hat is finished with grosgrain ribbon trim. Within twenty years top hats had become popular with all social classes, with even workmen wearing them. At that time those worn by members of the upper classes were usually made of felted beaver fur, while those worn by working men were made of rabbit fur; the generic name "stuff hat" was applied to hats made from fur. The hats became part of the uniforms worn by policemen and postmen (to give them the appearance of authority); since these people spent most of their time outdoors, their hats were topped with black oilcloth. During the early part of the 19th century felted beaver fur was gradually replaced by silk "hatter's plush", though the silk topper met with resistance from those who preferred the beaver hat. A short-lived fad in the 1820s and 1830s was the "Wellington" style of top-hat with concave sides. The peak of the top hat's popularity in the 1840s and the 1850s saw it reach its most extreme form, with ever higher crowns and narrow brims. The stovepipe hat was a variety with mostly straight sides, while one with slightly convex sides was called the "chimney pot". The stovepipe hat was popularized in the US by Abraham Lincoln during his presidency; it is said that Lincoln would keep important letters inside the hat.
