I have been thinking about getting this dress for a while, but was holding out because i was concerned it would look like a sack! but i am so glad i got it, and so glad my usual size was not available! typically i'm a m or a m petite but i ordered this in a s petite. while still flowy, i think it would have been overwhelming in my usual size. i think it will be great for many occasions as the solid black can be dressed up or down. i can't wait to wear it! definitely consider sizing down.
