I had no idea that there was a semiotics of lipstick! Rust red = all business? Rose = conversational? I had no idea! I wonder how often I've misread these signals?
Seriously, though, I also have no direct correlation between "makeup" and "not feminist." I assume that a feminist will wear whatever she wants, including makeup, whenever she wants, yes? Shouldn't you be able to wear matte lipstick when and where you want, A A, and be as feminist and feminine as anyone could be? I hope so.
