What do you mean by that? Did you buy a smaller size which later stretched out or you bought your normal size and it stretched out ?I really don't get this whole stretch thing. I have older pairs which have stretched out by a size or two and I have new stretch pairs which stay the same. I really really don't get it.I saw that 820s has an unusual composition. It has 2% elastane 6% polyester. What makes these jeans stretch?!
