Nothing! as far as clothes, Absolutely NOTHING!!! Wear Happiness. Laugh! Dance! Make Love! Be Merry! Spread Happiness not dread. It's over! Don't worry about it anymore. You ARE going to be alright after all. :) :) :) :)
Highly unlikely my friend. I would be elated to see you in person, from head to toe, clothed or unclothed. I, personally, will be unclothed. Big Giggles. Don't worry about it anymore, remember? It's the soul that shines through. :D! :D!
Sandals and cargo shorts. Nothing you could do about the world ending, why be uncomfortable. But don’t you worry, little lambs, you are extraordinarily unlikely to bear witness to the grim fantasies of Revelations in your brief lifetimes.
Live as if today is your last. It might be. Be comfortable.
