Petra started her research into America's First Nations Blackfeet tribe and was inspired by James, a Siksika boy who lives in the Blackfeet reservation. He encouraged her to make the collection entirely out of leather, the material his ancestors used to craft their clothes with, always using the entire skin of the animal. She took the original shape of the skin as a starting point, then weaving the leather as a construction for the shapes, but more important as a crucial symbol for strength in unity. This symbol is again reflected in the black model’s braided hairstyles.
