A 28GG bra fits a 28 inch underband with a ten inch difference between your underbust and the fullest part of your bust. Few high street ranges go down to a 28 back or up to a GG cup, let alone both together.
Most of our 28GG bras come from Freya, with Panache, Curvy Kate and Royce adding more. If the band feels tight, your sister size is 30G. If the cups overflow, go up to 28H.
Freya in a 28GG
Freya makes most of the 28GG bras here, with plunge, balcony and moulded T-shirt styles cut for a narrow frame. Shop the full Freya range.
Panache Balcony and Non Wired Styles
Panache adds balcony shapes and non wired options on the same 28 band, and Curvy Kate makes strapless styles. Browse the full Panache range.
28GG Sports Bras
Panache and Freya both make 28GG sports bras for running and high impact training. See all sports bras and the Freya Active range.
Checking Your 28GG Fit
If the straps dig in, the band is usually too loose and is not doing its share of the lifting. Try a band size down and a cup size up. Our bra size calculator and fitting guide explain how to measure at home.
