A 42FF bra fits a 42 inch underband with an eight inch difference between your underbust and the fullest part of your bust. Elomi makes nearly half of the 42FF bras here, and it is the only brand with plunge styles in this size.
Fantasie, Royce, Curvy Kate, Goddess and Sculptresse add more choice. If the band feels loose, your sister size is 40G. If it feels tight, try 44F.

Checking Your 42FF Fit
Check the fit in front of a mirror. The band should run level, the cups should be smooth with no gaping or spilling, and the centre should touch your breastbone. The bra size calculator and fitting guide take you through each step.
