For a look that's worthy of a modern sartorially savvy gent and casually sleek, team a black pea coat with a crew-neck t-shirt. If you want to easily play down your ensemble with shoes, introduce dark brown leather work boots to the mix. So as you can see, this outfit is a really good choice, especially for awkward transition weather, when the mercury is getting lower. This combination illustrates that as a 20-something man, you have a vast array of sartorial options.
