This pairing of a double breasted blazer and navy wool dress pants is perfect for smart situations. Add a relaxed twist to an otherwise mostly dressed-up ensemble by wearing a pair of black brogues. So if you're on a mission for a look that's stylish but also feels totally spring-appropriate, this just might be it. As a guy in his 30s, you want to start dressing with more sophistication. In this case, ensembles like this become a great source of inspiration.
