No, if you are a 30D, chances are you are tiny - a 0 or a 2, an extrasmall XS. A D cup on a 30 isn't very big (it is equivalent to the cup size on a 32C, 34B, 36A, etc), but sometimes you may have problems with the chest area for very fitted clothing as clothes that small tend to be supertight on the chest area. Good luck.
