So as you can see, it doesn't require that much effort for a man to look seriously stylish. Team a blazer with a charcoal crew-neck t-shirt and you'll look incredibly stylish. Complement your outfit with burgundy leather derby shoes to instantly shake up the outfit. As you can see, this getup is a really good choice, especially for summer-to-fall weather, when the temps are starting to drop. In your thirties, you probably want to start dressing with more class. That's when combos like this are a never-failing option.
