This combination of a dark green long sleeve shirt and a crew-neck t-shirt is very easy to imitate and so comfortable to rock a version of over the course of the day as well! For something more on the daring side to complete your getup, introduce charcoal athletic shoes to the mix. So if you're in search of a look that's on-trend but also totally spring-ready, this is it. And if we're talking casual clothing for mature gents, this ensemble is a good look on most gents.
