Mission failed.

It's not the clothes, or the activity that makes you stand out. It's the fact that from any distance, the immediate reaction that anyone will have, is, what is a woman in a dress doing out all alone in the middle of the night? That's what's going to draw attention to you. AFTER that, when they look more closely, will be when they realize that they're not looking at a woman in a dress, and that's when potential trouble will more likely arise. As long as you can get back to your car before anyone in the area gets to YOU, you're probably quite safe. The cleaning crew MIGHT notice and give you an odd stare, the kids at the drive through may at worst point and giggle, But since you're in your car, you're probably going to be fine. Unless, of course, you're visiting Homophobiaville somewhere. Then all bets are off.
