General: breasts

Soft round growths that serve as a secondary sexual characteristic for female or intersex characters. Breasts are often tipped with a nipple, or covered by a nipple_tuft.

If breasts are present in a scene, they should be tagged no matter if the character is clothed, or nude.

Some cultures consider bare breasts to be explicit, but this varies a lot by region. Since e621 is a global site, bare breasts should be rated Questionable.

Nicknames

There's a variety of nicknames for breasts. Breasts, boobs, tits, titties, hooters, knockers, jugs, ta-tas, melons, mammaries, etc.

Sizes

The full range of breast sizes can be approximated using the following tiered system. There will always be a few cases that are difficult to place in one category or the other; just do your best to fit them into one or the other.
