A 34FF bra fits a 34 inch underband with an eight inch difference between your underbust and the fullest part of your bust. FF is a UK cup size between F and G, so it is only made by brands that use full UK cup sizing.
Our 34FF bras come from Fantasie, Panache, Freya, Royce and Curvy Kate. If the band feels loose, your sister size is 32G. If it feels tight, try 36F.
Fantasie and Panache in 34FF
Fantasie makes most of the 34FF side support bras here, and Panache cuts underwired balconette bras with a lifted, open neckline. Shop the full Fantasie and Panache ranges.
Plunge, Full Cup and Non Wired 34FF Bras
Freya leads on plunge and moulded styles in 34FF. For full coverage there are full cup bras from Fantasie, Royce, Elomi and Sculptresse, and Royce makes most of the non wired options.
34FF Sports Bras
Freya, Panache and Shock Absorber make 34FF sports bras for running and high impact training, with Curvy Kate and Fantasie adding more choice.
Checking Your 34FF 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.
