There are seven regiments of the British army that guard the Queen and the Royal Palaces. Each one has a specific uniform that sets it apart from the others. The two regiments that make up the Household Cavalry are distinguished by the colors of their tunics, collars, and the plumes on their helmets. The Queen's Foot Guards wear full dress uniforms, which include a red tunic and bearskin hat, as they stand guard in front of Buckingham Palace and St. James Palace in London.
People often mistakenly assume that the traditional dress of England is the costume worn by the Queen's Body Guard, known as Beefeaters. Their scarlet and gold uniforms and distinctive black hats date back to 1552.
Scotland, Wales and Ireland all have national costumes. King Henry VIII commissioned an artist to create a template to create a national dress for England, but the artist did not deliver.
