Personally I just don't find the color appealing. Tans and camels can look nice, and for shows I like chili/whiskey/cognac/whatever you want to call it, but a dark brown anything will always look off to me. Not counting leather goods, my only pure brown (not counting camel or beige) piece is a pair of chocolate cords, which I don't wear too often. As of now I don't see myself buying anything with brown as a primary color (well, maybe a tie or pocket square, but not a suit or shirt or what not). That said, I see a lot of pictures here of neat outfits with an emphasis on brown (including the one here and the one in Carlo's thread, but I personally don't get them. I'll admit that it's just my hangup though, and I won't go off and call anyone who likes the look a "farmer."
