Post-First Wash
This pair of Levi’s Vintage Clothing 1967 505 jeans have been worn every day for four months straight, and washed about 7-8 times in the machine during this period.
After the first wash, your jeans will be less dirt repellent, and to go for months between each wash might be unrealistic. Nonetheless, you should wear your jeans as much as possible between washes.
