Denim is made to withstand a lot, so try not to wash it too much
as it really doesn’t need it. If you absolutely must, then the
cardinal rule is: no tumble drying.

Denim likes: being aired in public, or private, as long as air is
involved. It also enjoys being turned inside out if going in a
washing machine, and the coolest wash possible.

Denim dislikes: being washed too much, or hanging out with
impressionable friends (like paler fabrics) as it can get a bit
dye-happy when wet. Store it anywhere – it’s tough like that.
