What cup size is after DDD?

The most common cup sizes are AA, A, B, C, D, and DD/E. After that are cup sizes DDD/F, G, H, I, J, and K.

For G cup bra sizes and above, it's imperative that you choose bra styles that offer ample support. We recommend full coverage cups, sturdy underwire or reinforced bonding at the bust, and wide side and back wings.
