A royal mantle, or more simply a Mantle, is a garment normally worn by emperors, kings or queens as a symbol of authority. When worn at a coronation, such mantles may be referred to as coronation mantles. Many princes also wear such a mantle.

The Robe Royal (also known as the Pallium Regale, Imperial Mantle or Dalmatic Robe) is a robe worn by the British monarch when they are crowned at their coronation. It is donned just before the monarch is invested with the Orb, Ring and Sceptres. It is worn during the crowning and paying of homage.

Description. A coronation mantle of cloth of gold woven in coloured threads with a pattern of emblems in a curvilinear pattern of foliage, crowns, fleur-de-lis and eagles with coloured roses, thistles and shamrock woven over, and with gold fringing and lined in red tabby silk.

Traditionally the robes have an ermine cape with a long train made of crimson coloured velvet, trimmed in gold lace and lined with ermine. George V wearing his Robe of State at a State Opening of Parliament c.
