the sims are human and if you're going to apply human sizing terms to them they should be applied correctly.
the maxis default is a C-cup. bra sizes are obtained by taking two simple measurements. first you measure around the ribcage directly under the bust, add 5 inches to get your band size. then you measure around the fullest potion of the bust and subtract your band size. a difference of 1 inch is an A, 2 inches a B, and so on until you get to DDD (or F) which is a difference of 6 inches. this mesh has much more then a 6 inch difference between these two measurements, so unless she's wearing a molded cup bra, she's not a DDD--and even then she's probably wearing a size too big and got it stuffed with tissue paper.
