Reenactors at Hedeby, 2008 - short apron dress with side slits instead of gores, popular among the German reenactors (there's no existing remains of an apron dress that shows how long they were or if they had slits or gores) I like this idea!

Viking reenactment: a linen undergarment, a brown woolen dress with long sleeves, and an apron dress with silk decorations and metal posaments. Also a blue coat, a checkered shawl and a pair of needle bound mittens (dyed with yellow leek).
Note the fabric trim down the inside edges of this open-fronted apron dress. Also notice that the two sides of this open-front apron dress are being held together, at the top, by a cloak-type clasp, not a brooch.
