Put the dapper mode on in an overcoat and a navy and white crew-neck sweater. If you want to feel a bit classier now, complete your outfit with grey leather loafers. As a 30-something Millennial guy, you want to start dressing like an adult. If that's the case, getups like this become a great source of inspiration.
For a casually classic menswear style, wear an overcoat with a navy and white crew-neck sweater — these pieces go perfectly well together. For times when this outfit appears too perfect, dress it down by rounding off with brown leather casual boots. Sport this combo when you want to project a more professional image.
