A 42G bra fits a 42 inch underband with a nine inch difference between your underbust and the fullest part of your bust. It needs a firm, wide band and a deep cup together, which is why most 42G bras come from fuller figure specialists.
Elomi has the widest choice of 42G bras here, with Fantasie, Goddess, Royce and Curvy Kate adding more. If the band feels loose, your sister size is 40GG. If it feels tight, try 44FF.
Elomi Plunge and Full Cup Bras
Elomi makes all of the plunge bras in 42G and several of the full cup styles. Triumph, Royce, Sculptresse and Goddess add more full cup options for everyday support. Shop the full Elomi and Goddess ranges.
Side Support and Balcony in 42G
Fantasie cuts the side support styles in this size, and Curvy Kate and Panache make balcony bras for a lifted, rounder shape.
Sports and Non Wired 42G Bras
For exercise there are 42G sports bras from Elomi and Curvy Kate. Elomi also makes a non wired bra in 42G for days without an underwire.
Checking Your 42G 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.
