Main Street by Sinclair Lewis

The Jolly Seventeen (the membership of which ranged from fourteen to twenty-six) was the social cornice of Gopher Prairie. It was the country club, the diplomatic set, the St. Cecilia, the Ritz oval room, the Club de Vingt. To belong to it was to be "in. " Though its membership partly coincided with that of the Thanatopsis study club, the Jolly Seventeen as a separate entity guffawed at the Thanatopsis, and considered it middle-class and even "highbrow."

Most of the Jolly Seventeen were young married women, with their husbands as associate members. Once a week they had a women's afternoon-bridge; once a month the husbands joined them for supper and evening-bridge; twice a year they had dances at I. O. O. F. Hall. Then the town exploded. Only at the annual balls of the Firemen and of the Eastern Star was there such prodigality of chiffon scarfs and tangoing and heartburnings, and these rival institutions were not select -- hired girls attended the Firemen's Ball, with section-hands and laborers. Ella Stowbody had once gone to a Jolly Seventeen Soirée in the village hack, hitherto confined to chief mourners at funerals; and Harry Haydock and Dr. Terry Gould always appeared in the town's only specimens of evening clothes.
