Nice!
I wore denim capris last Saturday to the backyard house concert/picnic. I ended up crawling around on the grass quite a bit. Now, don't think nasty thoughts. It was because I was taking pictures so I moved around a lot. By the end of the day, I had grass stains on my knees but forgot about them and just threw the capris into the wash when I got home then threw them on this morning.
As I was driving in to work, I looked down and realized that the stains are still there on one knee. I only hope they're not also on my ass.
