We bring you a special episode from the Articles of Interest podcast hosted by Avery Trufelman about the incredible reach and adaptability of preppy clothes. It’s a story about the great modernizer of Ivy style, Ralph Lauren, and how he and his label, Polo, were themselves modernized by customers who helped push preppy in a whole new direction, from the runway to the streets.  We encourage you to listen to the entire American Ivy series from Radiotopia. Articles of Interest is created by Avery Trufelman. It’s edited by Kelly Prime, mixed and mastered by Ian Coss, fact checked by Jessia Siriano, with music by Avery, Rhae Royal, Sasami, and the Beazlebubs, the Tufts University Acapella Group.  Decoder Ring is produced by Willa Paskin and Katie Shepherd. We had mixing help on this episode from Sam Kim. Derek John is Slate’s Executive Producer of narrative podcasts. Merritt Jacob is Senior Technical Director.
