Naked, of course

Your very public announcement of becoming a nudist has strangely put you in the position that going fully nude to the party is actually your least provocative choice. That's absolutely hilarious to you. All this time wanting to get naked in public and now it's your most decent option. Why? Well, because if you wear clothes, you're going to lose them. It's basically a law of physics now. You can't keep coming up with ways to make it an accident forever. At some point, it'll become clear you're doing it on purpose. So, to be the good girl and not the exhibitionist slut, you have to go to a party with a bunch of your peers baring it all. God do you wish you moved here earlier.

Yes, everyone will eventually learn the truth about you and how much of a deviant you are. And, with your charisma, many people will learn to love you for it. But, you'd like to drag that out as long as you can get away with it. With that idea on mind, you bring a towel with you.

This serves two purposes. No, it's not for wearing. You read up on nudism and apparently it's a common thing to bring with you as a nudist to sit on. Makes sense. While you love the idea of sitting your bare ass and pussy on things, people that aren't pervs like you get squicked out by that kind of thing. The second purpose is to help you keep your cover. This party will last for hours. You will get horny. Drying yourself will be a very necessary task.

You drive over to the house where the party is and there isn't any parking near the house. That's because you realize that this is a block party. Jackpot!
