Currently reading "Amenhotep III, Perspectives on His reign. It is a complilation of several papers by different Egyptologists. I mention this here because in the 3rd paper (Chapter) by W. Raymond Johnson entitled "Monuments and Monumental Art" he repeatedly refers to Amenhotep III wearing a kilt and sporran. Here is a partial quote of one sentence "and pendant cords tipped with sedge-plant blossoms on either side of his sporran."

I guess kilts and sporrans have been around longer than we thought.
