I hunted with PH John Sharp in May 2015. On his website he states that camo is technically illegal but everyone wears it. When John picked me up in the Bulawayo airport, he was wearing camo shorts. So, I don't think it's a big deal, but I personally make it a point to not wear camo in the airports and around town. In the bush, not a problem. I also remember reading something about not wearing camo in Namibia, but again it was for public places such as the airport.
I Googled and found the actual law on the books in Zim and the key word that might be subject for interpretation is camo
uniform.

So it's sort like those old Dirty Harry movies: "Do you feel lucky"
