How did Amelia Earhart give her leather jacket a 'worn' look?

Earhart's commitment to flying required her to accept the frequently hard work and rudimentary conditions that accompanied early aviation training. She chose a leather jacket, but aware that other aviators would be judging her, she slept in it for three nights to give the jacket a "worn" look. To complete her image transformation, she also cropped her hair short in the style of other female flyers. Six months later, Earhart purchased a secondhand bright yellow Kinner Airster biplane which she nicknamed "The Canary." On October 22, 1922, Earhart flew the Airster to an altitude of 14,000 feet (4,300 m), setting a world record for female pilots. On May 15, 1923, Earhart became the 16th woman to be issued a pilot's license (#6017) by the Fédération Aéronautique Internationale (FAI).
