Chiefs of Clans
Chiefs have the right to wear their Crests as badges
Heads of large branches of a Clan, who have been Officially Recognised as Chiefs by the Lord Lyon King of Arms, may wear:
A person who has registered his or her own coat of Arms and Crest, or inherited these according to the Laws of Arms in Scotland from an ancestor who had recorded them in the Lyon Register, may wear their own Crest as a badge:
An armiger may also choose to wear instead the Crest badge of his Chief if the armiger is a clansman. An armiger is entitled to one silver eagle's feather behind the plain circlet, and if he is also a Peer he may add his appropriate coronet of rank on top of the circlet.
Clansmen and clanswomen
These are the Chief's relatives, including his own immediate family and even his eldest son, and all members of the extended family called the "Clan", whether bearing the Clan surname or that of one of its septs; that is all those who profess allegiance to that Chief and wish to demonstrate their association with the Clan.
It is correct for these people to wear their Chiefs Crest encircled with a strap and buckle bearing their Chief’s Motto or Slogan. The strap and buckle is the sign of the clansman, and he demonstrates his membership of his Chiefs Clan by wearing his Chief’s Crest within it.
