There aren't any full written reviews yet, but there is a comment on the review that says: "Everything about this costume is great, except the jacket. I found that it fit very tight through the arms and across the chest and was almost hard to button. My body is proportionate at size 18 (5'10,5'11), with C/D cup size."
You can also view the size chart for the costume to see if your measurements are near the listed measurements.
