Hi Shannon,
I checked out this skirt last night, plus the longer one that Angie showed in her recent ensemble.
This one IS thin, and as such you may find it a bit flimsy feeling. But it's not bad... I think I could handle it, but I know a friend of mine would find it too drapey. Now, I found it small. I am an 8 in BR pants almost always, but the M (8-10) was tight through the butt/hips. And the thin fabric couldn't handle that, if you know what I mean :). But sized up... it wasn't bad. On me, this meant it was then a bit big around the waist, but I think that's ok for a skirt like this. I know you've already ordered this, but for anyone else, you may want to consider sizing up, or trying two sizes. I'd be interested to know what you think of it, so please post when it arrives!
The long one is sheer genius. It has an inner skirt, so no worrying about what the slit does when you sit. It was actually almost too long on me... touched the ground, but I was doing a bunch of errands and didn't feel like taking the time to try on a Petite.
