If you're on a mission for a casual but also dapper ensemble, consider pairing a black leather shirt jacket with a white vertical striped crew-neck t-shirt. You can take a more refined approach with shoes and complement this look with a pair of black leather chelsea boots. Keep this ensemble ready to go when spring sets it, and we guarantee you'll save a ton of time getting dressed on more than one occasion. Interested in outfit ideas for over-30 men? This pairing is great inspo.
