Wash your jeans twice a year, say global denim experts
Next time your mother bullies you into throwing your jeans in the laundry, you can tell her that 'jeans experts' say that you should wash it every six months.

If industry experts are anything to go by , your mother for once might be wrong.
Unwashed denim should remain so for at least seven months
At the Amsterdam Denim Days, a celebration of all things denim held in Amsterdam last month, how-often-do-you-wash-your-jeans was a topic of much-heated, but ultimately inconclusive, discussion. For a city that calls itself the denim capital of the world, Amsterdam has many designers working exclusively with unwashed denim, and some of them, like Lennaert Nijgh, insist on not washing a pair of jeans for at least six-seven months. According to designer Lennaert Nijgh, "When you wear your pair of jeans for a long period of time without washing it, it starts to reflect your lifestyle. That's the point of unwashed denim. You make it into your own, however you like it. When you wash raw denim and it goes all soft, that's the fibres breaking down." On the other hand, Koen Tossijn, another Dutch designer who makes made-to-measure jeans, mostly for men, said that he wasn't anal about washing jeans.
Some major brands agree with the philosophy
Last year, Levi's CEO Chip Bergh said, "You should keep your jeans out of the washing machine." He added that he hadn't washed his jeans in over a year. Tommy Hilfiger once said, "I never wash my Levi's. They'll fall apart. I love them broken in." When asked about the idea of washing a pair of jeans after every wear, he said, "that's crazy".Television personality Anderson Cooper had also revealed that he wears the same pair of jeans every day and washes them only four times a year.
While going without washing your jeans for six months in the Indian summer sounds like a punishable offense, we still found denimheads who don't wash their favourite pair for as long as they can without assaulting their friends' senses (or risking the wrath of their mother), for various reasons.Says Bhavika Nanda, 24, "When I was in college I used to doodle all the time. On my desk, on paper, on my clothes. Sometimes I would doodle on my jeans, so I didn't like to wash them often. I washed them maybe once a month, and that too, when they got really filthy. My mother hated this the doodling and the not-washing part."
Kaushiki Kamthan, 26, says, "I wear jeans six out of seven days in a week, so if I start to wash them every time I wear them, they won't last very long.And since finding a pair that fits you right and is also the right colour is very difficult, I wash my favourite pair once a month in the hope that it will last forever."
But what to do when it gets dirty?
Just because you should avoid washing your jeans too much doesn't mean they won't get dirty especially if you're a klutz or if your job requires you to stay out a lot. So what do you do when you spill coffee on your jeans that was only washed last week? Nijgh thinks you should put your pair of jeans in the bathroom with the hot water on or put it in the freezer to kill the germs and the smell. But if you spill something on it, "Please just wash it."
Ankita Mehta, 26, says, "You can often find me rubbing cheap bathroom soap on my pair of jeans in parties because I spill things on my clothes a lot, but I don't like to wash my jeans." Kirti Singh, 22, says, "I read somewhere that putting jeans in the freezer helps kill germs, so sometimes when I feel like my jeans are smelling a little, I put it in a plastic bag and freeze them for a while. That helps. But if I feel the need to do that twice a week, I just wash it."
Tavishi Mathur, 26, says, "Even though I don't wash my jeans too often, I wash parts of them frequently . For instance, if I drop some food on them or they have a stain somewhere, I will put some detergent on that tiny part and wash it. I know that you shouldn't wash your jeans too often but I don't think you should walk around with food on them either."
