The Bavarian costume is called Tracht. Men wear the typical Lederhosen which are leather shorts that go to the knees while the women have the boob-boosting Dirndl. It is more common to see people wearing their Tracht when there is a special occasion such as a beer festival. However, you will see people also wearing them for weddings and is one of the reasons why Oktoberfest is such a popular time for pulling out the Tracht costumes. www.germanyja.com
