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. We know that there were only three well-educated delegates, who were William Brewster, William Bradfort, and Rev. John Robonson. Therefore, all delegates wore their garments to be well treated and to convey security in their ideologies as well as their struggles for United States Independence.
