 Suits in Britain were often made in tweed, often with three pieces, and were worn outside the City of London.Tweed is made from uncombed wool, and, like all fabrics from the time, was thick and durable (18-ounce was considered medium-weight in the Edwardian era).A full tweed suit is less common today, with just tweed sports jackets more often worn, but is still used generally as everyday wear by some, and for outdoor sports such as shooting and angling.
