So after reading a bunch of posts on the forum, I've decided to buy a pair of Nudie jeans for my first raw denim experience. I'm buying the following: Nudie 'Slim Jim' Slim Straight Leg Raw Jeans (Dry Navy Organic Wash). There seemed to be varying messages across the forum, so I'm curious. If my waist size is usually a 36-inch, should I buy 34-inch (one size down) to allow for stretching?
