How to Measure
1. Measure Your Band Size
Wrap a measuring tape snugly around your ribcage, just underneath your breasts. Make sure the tape is level all the way around and take the measurement in inches.
2. Measure Your Bust Size
Wrap the measuring tape around the fullest part of your bust. Keep the tape level and don’t pull it too tight. Again, take the measurement in inches.
