A 28DD bra fits a 28 inch underband with a five inch difference between your underbust and the fullest part of your bust. The cup is a common one, but the 28 back is not, which is why so many people struggle to find where to buy 28DD bras.
Most of our 28DD bras come from Freya, with Panache, Royce, Curvy Kate and Cleo adding more choice. If the band feels tight, your sister size is 30D. If the cups overflow, go up to 28E.
Freya Plunge and T-Shirt Bras
Freya makes most of the 28DD bras here, led by plunge and moulded T-shirt styles that sit close on a narrow frame. Shop the full Freya range.
Panache in a 28DD
Panache adds underwired styles, non wired options and balcony shapes on the same small band. Browse the full Panache range.
28DD Sports Bras
Panache and Freya both make 28DD sports bras for running and high impact training. See all sports bras.
Checking Your 28DD 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.
