Okay, the material is moderately thin and light, the leg openings are covered elastic (like it says), the waist opening is uncovered elastic (which is scratchy, but not a problem because when I do wear these I fold them down, I'll explain in a second).  I bought a 7, which is a comfortable size for me.  These are HUGE.  I hold them up and could wear them like a shirt.  Imagine if cotton Hammer Pants and Ed Grimley pants had a baby, and here you go.  Why did I keep them?  Because I didn't know how huge they were until I opened the package, prewashed them (I was in a hurry and just tossed them in without looking).  Do I wear them?  Sure.  They're great lounging pants without legs if you fold down the waist so they aren't riding your ribs : )
What can I say.  I guess I like the little patterns and the fact that they breathe.  Can I wear them with clothes over them?  Not a chance.
