I ordered both my usual size and a size down, and I'm really stumped as to fit.

The size down (6) are tiiiggght ... but if they stretch they might be okay.

My usual size (8) are fine as is ... but if they stretch might look a little saggy.

In my experience, non-premium denim does stretch out, especially around my thighs, (which are already big enough, thank you very much.) My DKNYs always seem to bag out after a few wearings. Still, I've never ordered down a size. Maybe that's the way to go?

Aargh! How on earth are you supposed to know?
