Even the uniforms of the 5th New York's were modeled closely on those of French "Zouaves": a dark blue Zouave jacket with red trim, a dark blue shirt with red trim, a red Zouave sash with sky blue trim, extremely baggy red pantaloons, a red fez with a yellow tassel, white gaiters and leather "jambières" ("leggings"). The 165th New York Volunteer Infantry was regarded as a sister regiment and known as the "Second Battalion, Duryee Zouaves". The 165th wore the same uniform as the 5th with the exception of the tassel of the fez, which was dark blue instead of yellow-gold. Photographic evidence suggests that later in the war the 165th was given replacement sashes that were a solid red color without the light blue trim.
