How does the dress and demeanor of the delegates to the continental congress suggest regional diversity?

The Continental Congress was a convention of delegates from the Thirteen Colonies who met May 10, 1775, in Philadelphia, Pennsylvania, soon after starting the fight in the United States War of Independence.

Their dress and demeanor were of great lawlords, which suggests a lot of wisdom, power and authority.
