I decided to order it and received my suit in the mail yesterday. The medium jacket fits perfectly (it has a bit of a looser shape anyway and doesn't button in the front), but the medium skirt is too big. However, I love the suit - it's perfect for what I need and soooo comfy - so I'm going to have the skirt taken in (could probably take about 3 or 4 inches off the waist). I ordered the pants as well, but those shipped separately and aren't here yet. Those will probably be too big too, so I'll probably take them in as well.

I'm so relieved that it basically fits - I had nightmares of trying to look all over town for a suit with a long skirt that fits, won't wrinkle in a carry-on, and doesn't look like something my grandma would wear!

So overall I'm pleased, although we'll see how well it does in action.
