Incredible dress in very good condition with no major signs of wear. I am calling it an extra small to small and have tried to measure for you the best I can -- please let me know if you need anything more specific. Lots of give and stretch. Covered in crystals and lace -- well constructed, halter style.
Armpit to armpit measured flat: 13"
Length from back to hem: 22"
Side length: 21.5"
Neck circumference 12.5"
