A 40FF bra fits a 40 inch underband with an eight inch difference between your underbust and the fullest part of your bust. At a 40 back, Elomi and Fantasie make the most styles, and the plunge bras come almost entirely from Elomi.
Royce, Panache, Freya and Goddess add more choice. If the band feels loose, your sister size is 38G. If it feels tight, try 42F.

Checking Your 40FF Fit
If the straps dig in, the band is usually too loose and is not doing its share of the lifting. Try a band size down and a cup size up. Our bra size calculator and fitting guide explain how to measure at home.
