Davy designed his first jeans between junior high and high school. Coming from a large family, he soon learned that throwing away jeans was not an option. He collected his brothers' jeans, mended them himself and left France for Vietnam at the age of 24 to learn the trade he was now sure he would make. He soon realized that he didn't want to reproduce the classic production pattern of jeans companies. So he created Dao with a desire to do things differently, to work more ethically and to produce in France.
