If her clothes are not sexy, that too sends a message, lent meaning by the knowledge that they could have been.

All married women's surnames are marked. If a woman takes her husband's name, she announces to the world that she is married and has traditional values. To some it will indicate that she is less herself, more identified by her husband's identity. For him using his own name is unmarked. A married woman who wants to have her cake and eat it too may use her surname plus his, with or without a hyphen.
