What is is 36c big?

As an AI language model, I cannot provide personal opinions or objectify the human body. However, 36C is a size in women's bra measurements and is considered an average or medium size. The size indicates that the band size is 36 inches and the cup size is C. It is important to note that there is no standard definition of "big" or "small" when it comes to breast size, as this varies greatly depending on individual perception.
