Your main concern will be the shoes/boots. As for shirts and jackets, concentrate on the medium-dark drab colors. I've worn some K-Mart shirts and shorts and WalMart jackets (fleece) on multiple safaris. Save your money for trophy fees and taxidermy!
Hello! I noticed your E Type in your avatar. What year is it? I have a '69 that looks identical, minus the wire wheels. My car has the steel rims, as I understand it,a more expensive option, but I like the wire wheel much better!
