Need to stop your suit trousers from falling off their hangers? Try the Savile Row fold, perfected over generations by the staff at London’s finest custom-tailoring emporiums. Start with the trousers upside down and straddling the hanger you choose. Fold one leg in through the hanger, dropping the bottom hem in between until its sit just above the crotch. Fold the second trouser leg over the first and through the hanger. Shake the hanger. Nothing happens. Clever, isn’t it?
