This look proves that it pays to invest in such smart menswear items as a white and black vertical striped long sleeve shirt and a brown suit. When this ensemble appears all-too-perfect, tone it down by rocking a pair of white leather low top sneakers. This one will play especially well when hot weather hits. As you slip into your 30s, you probably want to start dressing more like a mature gentleman. In this case, looks like this are a lifesaver.
