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.

No, a double D bra is not smaller than a regular D bra. It is actually one size larger. For example: A 34D has a bust measurement of approximately 38 inches. A 34DD has a bust measurement of approximately 39 inches. Since the cup volume increases as you go up the alphabet, a DD cup holds more volume than a D cup when the band size remains the same
