Wear a camel duffle coat with navy jeans to create a casually neat and modern-looking ensemble. Balance out your outfit with a dressier kind of shoes, like this pair of brown leather brogues. Seeing as it is getting colder with each day, this outfit is a great idea for the transitional season. As you reach your 30s, you probably want to start dressing maturely. If that's the case, getups like this become a great source of inspo.
