I think that the Europeans wanted to look like the Indians because with the Indiand being on the land before them it was how people were supposed to dress here. If a person travels to a foreign country even for vacation they tend to change their style even temporarily. When people move to foreign countries they try to fit in by becoming like the natives. Today people even dress like people from othe countires in their home lands because it's a fad.
French clothing is popular here and American clothing is popular in Asia.
When the French traders came here they would do anything for furs. They bought them fron thr Indians and often traded weapons or other supplies. Today in China they will give anything for a pair of Levi's. The Great Disease Migration.
