As I understand it, the Boston Light Infantry was a militia company, which adopted the zouave uniform in 1861 when it was the costume de rigeur. The 43rd MVM isn't recruited until late 1862 for 9 months, with the old BLI as the nucleus. They're sent to North Carolina, where there are a couple photographs made in '63, none of which shows any remnant of the zouave uniform of two years prior, nor is any mention made of it in Edward Rogers' regimental memoir.
Love the zouaves, too, but this unit doesn't sound like a prime example.
