I love that the seller contacted me BEFORE shipping to confirm I'd ordered the appropriate size. Now that I've gotten it, I could have even ordered a size smaller perhaps, but based on prior reviews saying it ran small, I figured it was safest to got bigger than smaller.  Looking at the pictures, the top fits me just as it does on the model, but the bottom seems a bit larger/longer. I'm 5'6", 170 lbs, semi-athletic, and a Medium might have worked. My shoulders are on the larger side though, and the size L I ordered works for them. This will be more of a "lounge around the house" dress than the casual event dress I wanted, but the fabric quality, etc. are all excellent, and especially the extra awesome customer care gets this a big "thumbs up" from me!
