Small breasts are larger than a flat chest and smaller than medium breasts. In other words, there's enough breasts to cast a shadow, yet the breast volume is less than the volume of a sphere with half the diameter of the character's facial area**.

IMPORTANT RULES: Characters breast should be evaluated with character in the standing position of the normal portrait picture (possibly a naked one) since close up and strange camera point of view can enlarge or reduce breast size perspective.
In case of borderline cases, always prefer to tag the character with the bigger size.
In case of enlarged breasts due to grotesque breasts/body modification just use: Grotesque Body Modification
