You’re a Sword Fighting Cloak Wearer!
You live by the sword and will likely die by the sword. When called for, you’ll challenge another to a duel. You also act as a protector to travelers from thieves, pirates, and other dangerous elements.
A swashbuckler needs a cloak that protects from the elements and from prying eyes. A nice brown or green will do nicely, and a hood is crucial and a secret pocket is always welcome.
