The sack coat or lounge coat continued to replace the frock coat for most informal and semi-formal occasions. Three-piece suits consisting of a sack coat with matching waistcoat (U.S. vest) and trousers were worn, as were matching coat and waistcoat with contrasting trousers, or matching coat and trousers with contrasting waistcoat. Trousers were shorter than before, often had turn-ups or cuffs, and were creased front and back using the new trouser press.[12]
