I'm not a woman, but I know many who 1. refuse to carry a purse; 2. are deeply unsatisfied with trends in clothing such as small pockets (and no they can't just wear men's clothes because women's bodies are shaped differently); 3. whose hands are too small to comfortably use a large (branded as "normal") or even medium (branded as "mini") phone.
There's a billion other ways women are being discriminated against every day. But yeah, it doesn't sell.
