Kleid
From AmtWiki
This style of kirtle was worn by Swiss and German women in the 13th to 15th centuries. It's is worn over a Hemd, a local style of chemise that is pleated in the front. Kleids have very full skirts and a plunging 'V' neckline. They can have long or short sleeves. Unlike other kirtles of the period the kleid had no waist seam, but instead was made larger by use of very large Gores.
