What size bra is DD?

A DD bra size indicates a cup that is larger than a D cup but smaller than an E cup. In terms of measurements, it typically corresponds to a difference of 4 inches between the bust and band size. For example, if someone has a band size of 34 inches, their bust measurement would be around 38 inches to qualify as a DD cup. It's important to note that sizing can vary slightly between brands, so trying on different styles is often recommended for the best fit.
