These breeches for a captain's uniform are a rare survival. In 1774 the uniform regulations were changed and blue breeches that were stipulated in the 1748 regulations were replaced with white breeches. These have a linen gusset in the back of the waist. The eyelets on either side were for linen tapes that would have been used to adjust the fit. The four buttons on each of the knees are of horn, faced with brass that has been die-stamped with the foul anchor motif.
