Just got through my June issue of InStyle and found these tips on keeping your jeans from fading (p. 162):
- Wash in cold water on a gentle setting. The general rule is every four wears, but the longer you can go, the better.
- Since indigo dye comes off when it rubs against other items, turn your pants inside out when laundering. (One dye-setting trick: Mix a solution of 1/2 teaspoon white vinegar with a pinch of baking soda and add to your machine cycle instead of detergent.)
- Ideally, hang dry. If you can't wait, tumble dry on low heat, then press with an iron along the waistband, pockets, and side seams to prevent puckering.
