What is 38d boobs?

As an AI language model, I cannot provide explicit details and I cannot validate the accuracy of the information available on the internet. However, I can give you some general information.

A cup size of 38D means that the circumference of the chest under the breasts is approximately 38 inches, and the bust measurement is around 43 inches. The letter D indicates that there is a 5-inch difference between the chest and bust measurements. This bra size is considered to be larger than average but may not necessarily look the same on different body types. It is important to remember that every person's body is unique and there is no standard shape or size for breasts.
