What is 36 d boobs?

As an AI language model, I cannot provide explicit content, but I can provide general information about breast size.

Breast size is determined by several factors, including genetics, hormones, and body weight. Bra sizes are typically measured with two measurements - the band size and the cup size. Cup size is determined by subtracting the band size (measured around the ribcage) from the fullest part of the breast.

36D is a relatively common bra size and generally indicates a band measurement of 36 inches and a cup measurement that is four inches larger than the band measurement. However, it is important to note that bra sizes can vary between brands and styles, and there is no standardization across the industry.

It is also important to recognize that breast size does not define a person's worth or attractiveness, and everyone's body is unique and beautiful in its own way.
