Hold on, let me just check the tree. Nope. Nah no loin cloth. Might as well wrap a towel. I'd rather just have my undies on if you think it is worth covering up.
I was really hoping on that fig leaf but undies are always good.
If you want to get really creative, grab a light sweater. 3/4 length sleeves if possible. Turn it upside down and put your legs through the arm holes. That'll look like shorts too...kind of LOL
I happen to be a fan of modesty and discretion so as far as I'm concerned, covering up is always a good thing.
