Hangerok

The hangerok (sometimes spelled hangerock or hangeroc) was a type of dress worn by Viking women and some other early medieval northern European cultures. The garment was shaped somewhat like a pinafore, with two straps over the shoulders secured by brooches. It would usually be worn over a tunic-dress called a særk or a kirtle (underdress).

Etymology
The word originates from German or Germanic Hängerock. Rock means skirt or (historically) dress in German, while hänger refers to the hanging of items from the brooches.
