In Berlin, my friend Sara told me that Stephen Prina, her teacher, always buys a pair of socks in every place he travels.
"But I'd be worried that I'd get all those socks mixed up and forget where I'd bought them," I said. I thought you'd have to buy fancy socks.
"No, he just buys regular socks," she said.
Imagine: A suitcase full of regular white socks bought in every place you've been. (Now that is style.)
