Why I've tracked every single piece of clothing I've worn for three years

Olof Hoverfält tracked every item of clothing he wore for three years. The data gathering enabled him to make extraordinary insights into the costs – both to his wallet and to the environment – of what he wore. His writeup is both a joyously nerdy statistical deep-dive and a series of genuinely useful insights, and it demonstrates just how carefully we must work to adjust our gut feelings about sustainability closer to reality.
