Women who self-identify as a feminist, above any other label that they might wear (attorney, professional, mother, sex goddess), generally buy into group taboos towards attire and grooming that would make them more attractive.
I am a woman, and a feminist, but being a feminist is not the sum total of my being. I relate far more to those aspects of myself that are professional, sexual, and maternal than I do that which is focused upon (in this generation) almost inexistent inequities between women and men.
I have an interest in BEING attractive, both to myself, and to the man I date (and other people, for that matter). Many hardline feminists reject the idea that women should be feminine AND a feminist. I don't. I will be laying tile in my house on Saturday and Sunday, and will probably be covered with grout/mortar, but on Monday, I will be doing training in front of a group, and will do my best to appear both feminine and professional.
I reject the idea that being feminine and caring about my appearance is buying into male objectification and is anti-feminist. But, in my experience, women who do buy into those ideas are generally butt-ugly.
I enjoy being sexy and/or attractive, and the idea of some militant feminists that women should reject this because it is a form of male patriarchy is simply something I will never do.
