FBA (Full Bust Adjustment)

A Full Bust Adjustment (FBA) is a sewing technique used to modify a pattern to better fit individuals with a larger bust. When standard patterns don’t accommodate a full or full-than-average bust, an FBA involves adding extra fabric to the pattern’s bust area, typically by smoothing or rearranging pattern lines. This adjustment provides more space and increases comfort, ensuring a better fit without altering other parts of the garment. Essentially, it’s a way to customize a sewing pattern for a fuller chest, resulting in a more flattering and comfortable finished garment.
