Rule #1: Treat your raw denim like Tyson treats hookers.
Rule #2: bathe your raw denim as though they were a homeless kid in the slums of El Salvadorian gang territory.
Prerequisite #1: Have a partner who loves you, even though you smell like said El Salvadorian homeless vagabond.
Prerequisite #2: Don't work a desk job, or any other job that does not require Tyson-esque treatment being done to, or in, your hookerish pants. Gainful employment for great raw denim: Macguyver, James Bond, Tim "The Tool Man" Taylor, Mary Kay Laterno.
