I think the ripped jean look is ridiculous, unless you're at home working in your yard or just lounging around.  But I think it would be a disgrace to go out in public looking like this, unless of course, a person doesn't have anything else, and then it's perfectly acceptable.

I also see the dirty jean look, and that looks just as bad.  If I wanted this look, all I'd have to do is roll around in the dirt for a while.

I find it hard to believe that people have bought them off the rack that way, and have paid through the nose for them, to boot.

I personally think it looks dumb.
