grey Royal Gibraltar Regiment Frock coats One type of frock coat may be worn by officers of lieutenant general and above (and major generals in certain appointments) on formal occasions when not on parade in command of troops. They are a knee-length, dark blue, double-breasted coat with velvet collar and cuffs. It is usually worn with the peaked cap but is occasionally worn with a cocked hat by certain office-holders such as the Major-General commanding the Household Division, Gold Stick and Silver Stick and the Constable of the Tower. A different type of frock coat is worn by certain officers of the Household Division, Honourable Artillery Company and King's Troop of the Royal Horse Artillery. These are also dark blue but are single-breasted and with ornate black braiding and loops. Similar braided coats are worn on occasion by directors of music and bandmasters of bands affiliated to line cavalry regiments (in other bands they wear a plainer double-breasted frock coat similar to that of senior officers but without the velvet) in dark blue (or green for The Rifles).

It is not generally issued to all units, with the khaki No. 2 Dress functioning as the main parade uniform. No. 1 dress originated in the "undress" uniforms ('blue Patrols') worn for semi-formal or ordinary duty occasions in the late 19th century. It was first issued in its current form for the 1937 Coronation, intended as a cheaper alternative to the full dress uniforms that had been generally withdrawn after 1914. It became known as No. 1 Dress in 1947. Army units participating in the 1953 Coronation wore the new uniform as a temporary issue. For most units, No.
