Go for a straightforward but classy outfit by wearing a black corduroy blazer and a red long sleeve shirt. To introduce a dose of stylish effortlessness to this look, complement this getup with beige athletic shoes. So as you can see, it's super easy to look seriously stylish and stay toasty when colder weather comes, all thanks to looks like this one. This combination demonstrates that cracking the fashion code as a guy in his twenties is not particularly hard.
