Pete and Trudy Campbell invite you to consider joining or renewing your annual membership with the Preppy Anti–Defamation League. Summer is go–to–hell season, a time when Madras plaids in blinding primary colors, which have caused traffic accidents, and radiant Lilly Pulitzer tropical patterns are worn to the consternation of the legible-clothing-wearing general public. Other than your trust fund, a membership in the Preppy Anti–Defamation League is the best support mummy and daddy can give.

I get the appeal of madras plaid in small doses but have never understood how a woman can wear Lilly Pulitzer prints.
