I am so disappointed that I will be returning this dress.  I loved it, but it is a tad too snug and too short.  If it were 2 inches longer, I would probably keep it as I love the fabric Modal.  I am 5'4", 115 lbs, slim build with a little bit of a stomach (thanks to SIBO) and I usually wear a size S.  I like my maxi dresses long, but not dragging on the ground.  If you look at some of the other colors, the dress looks shorter on the model than the black dress.  I also ordered the Pastel by Vivienne dress in Navy in S and love it, so I ordered another in black.  Not sure I like it as much in black.  I am considering ordering the XMING dress in black, so I'm still in the search for a black maxi dress to complete my array of maxi dresses.  (Also ordered the Zattcas in Olive, which I like very much).
