A blazer and an aquamarine long sleeve shirt are the kind of a never-failing ensemble that you need when you have no extra time. For an on-trend hi/low mix, add a pair of dark brown leather derby shoes. If you're often not sure how to dress appropriately for your age but also look stylish, this ensemble is a practical example.
Wear a blazer with an aquamarine long sleeve shirt to look modern and classic. Finishing off with a pair of navy and white low top sneakers is a fail-safe way to add a dose of stylish effortlessness to your look. As a young guy, you probably want to start dressing like an adult man. If that's the case, combinations like this are perfect as inspiration.
