As worn for national dress, the bodice is decorated with silver embroidery featuring a princely crown in the middle of the bodice. Accessories include a black wheel-shaped bonnet featuring silver embroidery, white lace gloves, white stockings and black shoes with a silver buckle. Other variations include floral headbands () or crown-shaped headpieces (). The current designs have been in use since at least the 1930s, but their origins can be traced much earlier. Similar designs have been found in archaeological remains from Vaduz, Gamprin and Eschen. Especially notable is an excavated church graveyard in Mauren from around 1700, which included well-preserved garments and a bonnet. In the German diaspora Outside its countries of origin, the dirndl has become an ethnic costume, worn as an identity marker by members of the German diaspora. This term refers to German-speakers and their descendants who live in countries where German is a minority language. German, Austrian, Bavarian and Scandinavian people migrated to North America in the 19th century. Germans made a strong contribution to the gene pool of Montana, Minnesota, the Dakotas, Missouri, Wisconsin, New York City and Chicago. The German American ethnic group () are their descendants in North America, and form part of the worldwide German diaspora. Beginning in 1920 and especially after World War II, many Danube Swabians migrated to the United States, Brazil, Canada, Mexico, Austria, Australia, and Argentina. Across the United States there are dozens of German-American cultural or heritage clubs, such as the Donauschwaben heritage clubs. The clubs host events and festivals (such as Von Steuben Day parades) to preserve and celebrate their heritage with the surrounding communities. During these festivals, participants often dress in traditional outfits such as dirndls and lederhosen. Dirndls and lederhosen are also worn as party clothing at Oktoberfest celebrations around the world. This is especially the case when the celebration takes place in a German diaspora community, such as the Oktoberfest celebrations at Colonia Tovar in Venezuela or the Fiesta Nacional de la Cerveza in Villa General Belgrano, Argentina.
