How big are DD cup size bras?

DD cup size Bras typically have a breast volume that is larger than a D cup but smaller than an E cup. The exact measurements can vary between brands, but generally, a DD cup corresponds to a difference of about 5 inches between the bust and underbust measurements. This size is often considered a fuller bust, accommodating a larger breast volume while still providing support and comfort. It's important to try on different styles, as fit can vary significantly across different manufacturers.
