A 42GG bra fits a 42 inch underband with a ten inch difference between your underbust and the fullest part of your bust. Elomi makes more than half of the 42GG bras here.
Royce, Goddess, Sculptresse, Panache, Fantasie and Curvy Kate add more choice. If the band feels loose, your sister size is 40H. If it feels tight, try 44G.
42GG Sports Bras
There are two 42GG sports bras: the Elomi Energise and the Curvy Kate Everymove. See all sports bras.
Elomi Plunge and Underwired Bras
Elomi makes all of the plunge bras in 42GG, including the Elomi Sachi, plus the underwired Elomi Morgan and Elomi Zarla. Shop the full Elomi range.
Full Cup, Balconette and Strapless
For full coverage there are full cup bras from Elomi, Royce, Sculptresse, Fantasie and Goddess. The Panache Tango is a balconette option, and the Goddess Verity is a strapless bra in this size.
Checking Your 42GG 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.
