Today's Everyday Fashion: The Sheath Dress

If I could clone this dress I would - I'd make similar ones in bright colors and patterns. I have a lot of sheath dresses in my closet, but this is the only one with sleeves. When I was shopping the other day I looked for sheath dresses with sleeves everywhere, and all I found was: 1. sweater material, 2. no shape (shift dress), 3. or stretchy material. I definitely don't want stretchy, but I still want some (structured) shape to it, and at least a quarter length sleeve (now I just sound picky). I found a few below but they still seem to be tough to find. What are the hardest dress styles to find in your experience?
