I have a quick question. I just got some robert geller jeans, and they are just a bit too big in the waist and thigh area. This is based on my first wear of them right out of the box. They are not raw denim. Will they still stretch to get even bigger? I was going to bring them to my tailor to taper them, but I wanted to know if I should wash them first to see how much they shrink. Is washing them still not recommended even if they are not raw?
