A 34GG bra fits a 34 inch underband with a ten inch difference between your underbust and the fullest part of your bust. A GG cup on a 34 back is well past where most high street ranges stop, which is why the choice comes from fuller bust specialists.
Our 34GG bras and lingerie come from Fantasie, Freya, Elomi, Panache and Royce. If the band feels loose, your sister size is 32H. If it feels tight, try 36G.
34GG Full Cup Bras
Royce, Fantasie, Elomi, Panache, Sculptresse and Goddess all make full cup bras in 34GG, the most secure choice for everyday wear.
Fantasie and Freya T-Shirt Bras
Freya and Fantasie make most of the moulded T-shirt bras in 34GG, for a smooth line under fitted tops. Fantasie also cuts the side support styles. Shop the full Fantasie range.
Plunge and Sports Bras in 34GG
Elomi leads on plunge bras in this size. For exercise, Panache, Freya and Shock Absorber make 34GG sports bras.
Checking Your 34GG 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.
