I bought the "light grey" color. the dress in the photo does not look a thing like the dress in person, it does not look grey at all but more of a light teal/light blue.  it is absolutely gorgeous and has a slight swing shape. i took my normal size xs.  the end of the sleeves (where the buttons are) are very tight but still fit, you just have to be careful taking off or else undo the buttons.  also online inventory says no one has this in store, but i did end up finding it (rockefeller).
