What is is a 32d the same as a 34c?

No, a 32D and 34C are not the same size. The band size is different between the two. The number in the size (32 or 34) refers to the measurement around the ribcage just beneath the bust, while the letter (D or C) refers to the difference between the bust and ribcage measurements. A 32D means the bust measurement is 4 inches larger than the ribcage measurement, while a 34C means the bust measurement is 3 inches larger than the ribcage measurement. Therefore, a 32D bra is smaller in band size but larger in cup size compared to a 34C bra.
