Cassfeminine, also known as cassfem, is a subset to cassgender where one feels that their gender is unimportant or where one is indifferent to the idea of gender, but knows that their gender is feminine in some way. Cassfeminine is different from a lack of gender, as a cassfeminine individual might have a gender but not feel that it's an important part of their identity, or they may not care about anything past the fact that their gender is more or less feminine.
The masculine counterpart is cassmasculine.
