The master class may be effective at replicating its genetic code, but it doesn't seem to have been very good at perpetuating its dress code. Certainly the archetypal WASP Ivy League look that dominated the 20th century via suppliers like Brooks Brothers, J. Press and F. R. Tripler has dwindled to near-museum status. I would guess that no Yale graduate of the last quarter century has sought to honor the memory of Dean Acheson, John O'Hara or other master-class clotheshorse of The American Century.
