Measurements taken laid flat: Doubled at bust, and waist.
Because this is an open front, measurements are easy fitting.
Shoulder to shoulder: 15.5″
Bust: 19.5′ I measured this from armpit to armpit across the back. Its NOT doubled as per my usual. This is just to give you an idea, but its obviously a flexible fit.
Waist: free
Shoulder to bottom hem: 50″
