I believe this is a size 1, equivalent to a Small. Color: Blue Purchased over 5 years ago and worn a few times. The neckline can be adjusted. You can wear it like the first photo, showing the décolletage, or thread it through the loop in the back to cover it up, as shown in the fourth photo. To keep shipping costs down, I plan to fold it as small as possible for shipping. Thank you for your understanding.
