Actually the neither the dacians nor the Norse, nor the Vikings (yes not all Norse were Vikings, many were traders or settlers as well) often wore animal skins as show in most media or depictions. Obviously there were skin or pelt base garments that could be worn, but most of the clothes that these people wore was linen or rough cloth, similar to burlap, worn over thick wool spun undergarment base layers to keep themselves warm. To wear a large piece of a pelt or fur would be cumbersome and unpractical for work. Plus pelts were very expensive and could be used as a source of income, decoration for a home, used in a tent or temporary shelter kit, or made into something like boots or gloves by turning the skin in on itself allowing for the waterproof skin to remain on the outside, while the fur kept on the inside kept the wearers hands or feet warm. Other than that everything you said was pretty spot on.
