the regiment wore the standard 1768 uniform of close fitting, long tailed red coat, white waistcoat, white breeches and stockings with black gaiters, black shoes with buckles and a black cocked hat. the grenadier company wore tall black bearskin caps, whilst the light infantry company would have worn some form of light cap and short spatterdashes rather than gaiters. it was common practice for grenadiers in the field to abandon their bearskin caps in favour of the more practical cocked hat. because the 83rd was a royal regiment it was entitled to have royal blue 'facings' (collars, cuffs and lapels) augmented by white lace on the button holes. officers wore an identical uniform, except that the coat was made of a superior scarlet cloth and the lace was gold. however this was usually only worn on formal occasions, and for everyday wear it was usual practice to wear a cheaper cloth, unlaced coat. two types are button are known to have been used. one was a circular, flat gilt metal button 22mm in diameter, with a simple scroll and dot design surrounding the number '83'. on the back was born the inscription 's. firmin - strand 1771-1780'. the other type was circular, pewter and 24mm in diameter. the inscriptions on the front and back were identical to the gilt version, except without the scroll and dot decoration.
