When one talks about a safari jacket the image that comes to mind is that of a middle-aged man wearing a sand-colored shirt jacket that fits loose and long. The look is colonial and rather unflattering. There is no shaping in the waist and has loose sleeves in an effort to remain cool while on an African safari.
But in the last year or so the safari jacket has seen a come back albeit with a modern interpretation. They are either made like a shirt or a coat depending on the maker. My preferred version is the one that is made like a shirt, in other words, unstructured, cut to fit over another shirt and made with a heavy, textured cloth such as linen.
