A dirndl is a national dress worn by German women. Not everyone is aware of its name, but its appearance is always associated with German culture. This attire consists of a bodice, blouse, full skirt, and apron. As the dress is quite popular, it may be made of quite cheap materials and fabric, but properly made dirndl can be really expensive. A proper dress is tailored and sometimes cut from costly hand-printed or silk fabrics.

Where does the name come from? In the South German dialects (Bairisch), Dirndl originally referred to a young woman or a girl, and Dirndlgewand to the dress. Nowadays, Dirndl may equally refer to either a young woman or to the dress.
