It’s hard to imagine, but at this point, with six articles of clothing, I in fact have twelve different outfits. Okay, twelve different, really REPETITIOUS outfits, but this would in theory be “do-able” for a while. Remember, nobody is keeping track of what you wear (if they are, they’ve got bigger problems than you can solve), and you can always get laundry done while traveling. Accessories could brighten this up quite a bit, too.
A couple more tops, including another grey tee shirt, to wear on the flight home.
