the Four Hundred
The wealthiest and most powerful of the social elite. The phrase allegedly originated from the number of people that Caroline Schermerhorn Astor (wife of US millionaire John Jacob Astor) could fit inside her ballroom. Primarily heard in US. Thanks to my new husband, I am now part of the Four Hundred and the recipient of many jealous looks.
