Chicago corporations commonly operate a business casual dress
code with smarter casual clothes in subdued colours often worn
with a suit jacket. In most client-customer business situations
more formal clothing is worn, typically a business suit.
During the summer, choose natural fabrics to help counter the
heat and humidity. In the winter warm clothing, including a
thick full length coat are advisable to combat the freezing
outdoor temperatures.
Greeting someone in Chicago
A handshake is the usual greeting throughout the United States.
Most people address each other by their first names, but at
business meetings and formal functions, the using of a person's
title and last name is preferable.
