Hi,
Im off for a month in the Kruger soon and had the same problem, i got some green GS shirts off Ebay and removed the epaulettes so as not to look quite so military. I notice that there is a Khaki colour as well im not sure if this is what your after but they are so cheap it might be worth getting one to have a look!. There are loads on there at the moment (these are the ones i mean)
