Raw denim ages beautifully. The material will show individual characteristics – the variable texture of the yarn, the pattern of the fade and the slight twist to the seams which will be unique to you. When new, the indigo dye can transfer on to other fabrics, surfaces and skin. Over time this loss of colour will reduce.
There are endless debates about how often you should wash denim, and whether you should leave your jeans for six months before washing. It’s a personal choice and partly depends on how often you wear your jeans and what you do in them.
The way in which raw denim fades is a result of the dye on denim cloth being only present around the outside of the thread, leaving a white core. (Think of a stick of blue rock.) The longer you go without washing your jeans, the more the dye will be rubbed off during the day to day wear, revealing the white thread underneath. Your jeans will develop an individual fade and look, based on how you wear them. If, on the other hand, you wash your jeans regularly, they will develop a more uniform fade. The choice is yours.
Always wash your jeans separately. Turn them inside out and wash, preferably in cold water, or at a maximum temperature of 30 degrees. Do not tumble dry. Iron inside out on a warm setting if needed.
