Preferred outfit is lower undies only, but I guess for formal affairs I could throw on a t-shirt. And, since the Palace would be located in a sunny, warm locale, barefoot or flipflops. All out of shape people would be required to don t-shirts only(nothing worse than seeing a man with boobs bigger than my own!!)
Edit: I felt qualified to answer since I was, quite literally 'born a King'....think about it
