The line between yes and no is a very thin one. It is thin in action, thought, emotion, and even, oddly enough, Attire. When we go out of an evening dressed to entice and attract, we walk a slim line. We do so, all unknowing, because those we may attract might not be the ones we want. So when we dress ourselves in ways that are overtly sexual, and deliberately provocative, we take a chance that those who see us will read our message correctly. Of course what so often happens is quite the reverse. So often, (and this is particularly true to men), such apparel reads as an invitation to sexual conduct that may not actually be desired, at least, not with that person. And as a gay man, tight jeans and tank tops are not always an invitation to more than conversation, as I have learned myself from both sides of the issue.
What this means is that the clothing we select when we go on the prowl is something double edged. Sure it makes us feel attractive and powerful. Sure, it's designed to make the people we most want to notice us, see us in a positive way. But we must be aware of the other side.
Just as great political freedom requires diligence to maintain it, greater freedom of behavior and dress requires diligence, and observation, to insure we do not substantively harm others in some way.
