What to Wear?

We're in Cleveland, TN, just outside Chattanooga, where we're visiting our friends Lee and Cynthia. We've just spent a great evening together, but Cynthia is determined to take me to a tearoom for lunch tomorrow. In fact, she's even made reservations. Here's the problem. I'm traveling light on this adventure -- when you only change clothes every three or four days, you don't need much -- so I've got exactly three pairs of sweatpants, a couple of t-shirts and my old lady, white, zip-up tennis shoes. And two of the sweatpants are filthy. I told her I'm not going to go out and buy an outfit (including shoes) just for lunch. Well, she's saying we'll figure something out. I may be the worst-dressed person ever to enter what has been chosen as the best tearoom in Tennessee.
