If a woman’s clothing is tight or revealing (in other words, sexy), it sends a message — an intended one of wanting to be attractive, but also a possibly unintended one of availability. If her clothes are not sexy, that too sends a message, lent meaning by the knowledge that they could have been. There are thousands of cosmetic products from which women can choose and myriad ways of applying them. Yet no makeup at all is anything but unmarked. Some men see it as a hostile refusal to please them.
