Beautiful illustration by Carol Rossetti. Don't cage yourself for not being conventional. Societal standards of beauty change every 10-15 years. There are more important things in life. Character, ambition. Your body is a tool for you to use, it is not you in and of itself.
Feminism is the advocacy for women's rights on the grounds of social, political, and economic equality to men. If you try and twist feminism to be an asshole - you are not being the right kind of feminist. Feminism is not synonymous with misandry.
