Brazzaville - Post Report Question and Answers
What is the typical dress code at work and in public places? Is formal dress ever required?
For the embassy, it is business and business casual. For those who will work closely with local contacts, it is highly recommended to wear suits and/or business attire. Causal attire can be worn when out and about in the city (shopping, get togethers, events). The embassy does not have a formal MSG ball, but in recent years there has been an MSG cake cutting ceremony and formal attire (tuxes and formal dresses) can be worn to this event. - Jul 2020
