Images or animations depicting cleavage; sometimes called the "bust line", the gap between a character's breasts, lying over the sternum. "Cleavage" is not to be tagged on an image if the character is nude, as cleavage is to be expected. Rather, tag it on images where their cleavage is exposed by the clothes they are wearing, usually a garment with a low neckline, such as ball gowns, evening gowns, swimwear, casual tops and other garments.

In the unlikely event you see cleavage caused by pecs, or moobs, don't use this tag. Use pec_cleavage, or moob_cleavage instead. Do not worry if the tags are empty now. The cleavage tag is only for breasts.
_{If there is a better name for such concepts, feel free to modify this suggestion.}
