Sunday School: Dressing With Etiquette Part VI

http://www.corralitoshistory.com/families.html

Back in 1918, there were even etiquette rules for the proper attire when going to church:

For church wear, a quiet, rather simple street dress, which does not proclaim that either money or time has been spent upon it to any notable extent, is by far the most appropriate.  The suit should be becoming but inconspicuous.

From: The Etiquette of To-day, Edith Ordway (1918)
