A 30GG bra fits a 30 inch underband with a ten inch difference between your underbust and the fullest part of your bust. It has the same cup volume as a 32G and a 34FF, carried on a firmer, narrower band.
Our 30GG bras come from Freya, Fantasie, Panache and Curvy Kate. If the band feels loose, your sister size is 28H. If it feels tight, try 32G.
Fantasie Side Support in 30GG
Fantasie makes most of the 30GG side support bras here, which bring the bust forward for a narrower shape. Shop the full Fantasie range.
Freya T-Shirt and Plunge Bras
Freya leads on moulded T-shirt bras and plunge styles in 30GG. Panache, Fantasie and Royce make full cup bras for more coverage.
30GG Sports Bras
Panache, Freya, Curvy Kate and Fantasie make 30GG sports bras for running and high impact training.
Checking Your 30GG Fit
The band should sit level around your back and feel firm on the loosest hook. The centre of the bra should lie flat against your breastbone, and if it lifts away, try the next cup up. Use our bra size calculator or the fitting guide to check your size.
