The colors of a briefcase for men must be either black or brown, but it is advisable to have two briefcases, one black and one brown so that you can wear them alternatively, depending on the outfit. The briefcase is, without a doubt, one of the most classic and pretentious accessories, as it requires special attention in choosing it so that it is both practical and elegant but also stylish at the same time. According to designers, a man's bag is an extension of his personality.
