There are many things throughout a normal woman's day that require her to wear clothing. The fantasy of women being nude all the time is the fantasy of women having nowhere to go and nothing to do. It's a fantasy for a mindless, purposeless woman. It's not our fantasy - we love thinking women, purposeful women - so occasionally our models wear clothes. And occasionally they don't. If they wear clothes it's because it suits their purpose, their job, their situation, or the style of photography. If they don't, it's not because they're mindless but because they think - they think it will be fun, or sensual, or erotic, or beautiful. Only a woman who thinks would want to be naked. And it's only beautiful if she is nude for a reason.
