Hi, I'm interested in the Michael Kors jeans but I can't tell if they use a stretch denim or not.
Let me check that out for you

Are you concerned that they may or may not shrink after washing?
No, I just move around a lot for my job and having the pants stretch is very helpful.
It appears that most of their denim is made of mostly cotton and in some jeans they are blended with some stretchy materials. They won't be super stretchy unless they are advertised as such. Otherwise you can expect the mobility of typical jeans
Okay, that's what I needed to know!
Awesome, glad I could help? ! Hope you have a great day :)
