The underbust and overbust measurement helps you determine your bra size based on your body measurements.
To use this chart:
- Measure your underbust (below your bust) using a tape measure.
- Measure your overbust (around the fullest part of your bust).
Match these measurements in the chart to find your bra size. The chart combines band sizes with cup sizes for accuracy. For example, if your underbust is 32 inches and your overbust is 36 inches, your size could be 32B.
