This combo of a brown blazer and a crew-neck t-shirt looks sharp, but it's also super easy to wear. Tap into some Idris Elba dapperness and complement your look with a pair of dark brown leather loafers. So as you can see, this combination is a really smart idea, especially for weird fall weather, when the temperatures are starting to drop. As you can see here this look is something you can totally wear as a 30-year-old man.
