These breeches for a Captain's uniform are a rare survival. In 1774, the uniform regulations were changed and blue breeches, which were stipulated in the 1748 regulations, were done away with in favour of white. 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.
