Lipstick feminism is a belief that women should be able to express their femininity and their beliefs at the same time. It's like when you wear your pretty dress and also stand up for what you believe is right. Lipstick feminists say you don't have to choose between being girly and strong.
It's like if you want to wear lipstick because it makes you feel confident and pretty, you can still stand up for women's rights and gender equality. You don't have to be one or the other. You can be both!
The idea about lipstick feminism is to show the world that you can be feminine and still powerful at the same time. It's a way of fighting against the idea that women who care about looking pretty can't also be smart or powerful. Lipstick feminism is about breaking those stereotypes and showing that women can be whoever they want to be, regardless of what other people think.
So, it's like saying, "I can wear pink and still kick butt!"
