The all blue frock-coat worn by officers in undress was re-introduced in 1852, having been abolished in 1848. The 1848 coat was single-breasted, high-collared and had detachable, elaborately laced and embroidered shoulder ornaments. The officer in this photo wears the frock-coat worn from 1852 to 1867. The double-breasted front had two rows of large gilt buttons, 8 in each row, and three smaller buttons on each cuff flap. Similar flaps were on the back skirts and extra buttons at the waist. On the left shoulder was a twisted crimson silk cord to hold the crimson silk sash in place. The cord buttoned at the collar with a small gilt regimental button. When this frock-coat was discontinued in 1867 it was replaced by a short blur patrol jacket with black silk embellishments.
The undress forage cap is of blue cloth with a black silk cap-band of oak-leaf pattern lace. The embroidered badge of Britannia on the front is worn over an embroidered numeral 9. The black button on top of the cap was added c1860. His sword is kept in a black leather and gilt scabbard slung from white leather slings attached to a white waist-belt. This uniform is worn with dress trousers, ankle boots and white gloves.
