For a look that's refined and envy-worthy, wear a light blue vertical striped long sleeve shirt and charcoal wool dress pants. Put a relaxed spin on this ensemble by finishing with dark brown leather high top sneakers. As you can see here, it's super easy to look sharp and stay toasty when chillier weather hits, thanks to this look. As you mature into your 30s, you probably want to start dressing like an adult man. That's when inspo like this comes in handy.
