Haslach’s 17th-century former Capuchin monastery houses the Schwarzwälder Trachtenmuseum, showcasing flamboyant costumes and outrageous hats, the must-have accessories for the well-dressed Fräulein of the 1850s. Look out for the Black Forest Bollenhut, a straw bonnet topped with pompons (red for unmarried women, black for married) and the Schäppel, a fragile-looking crown made from hundreds of beads and weighing up to 5kg.
