Well, I consider myself a feminist and Madonna isn't my role model for *anything.* I think there's a huge difference between lipstick feminism and "slut feminism," too.
In my opinion, lipstick feminism simply means I am secure in my femininity and I am not ashamed or afraid to be a woman. I wear makeup because I like it, not to attract men or sexualize myself. I have no interest in looking like a slut. Neither am I particularly fond of the unwashed look affected by so many in the 70s for the cause of feminism.
Here's the thing: even a patriarchal society expects the males of the species to be decently groomed and clean when they show up for work. It is absolute equality to expect women in the same positions to adopt the same standards. Makeup and mile-high heels are optional, but being neat, clean and nicely dressed is not an option, in my opinion. And if that's "lipstick feminism," so be it. I call it being a mature adult.
