Stoosh brown dress up pants, juniors size 7

These pants are comfortable and make your butt look good 😄 as I was taking the picture I noticed that on the back of the pants towards the lower end of each pant leg there is a fainted line that’s a lighter brown as seen in the second pic. I’m not sure what I bumped into but I never noticed it all along until now lol. The pants have a nice flare to them as well!
