Is cup size double d bigger than cup size e 75?

Cup sizes can vary between different sizing systems, but generally, a double D (DD) is larger than an E cup. In many sizing systems, the order from smallest to largest is typically A, B, C, D, DD (or E in some regions), and then E. Therefore, a DD cup is usually considered to be bigger than an E cup, but the exact fit can depend on the brand and style of the bra.
