A black blazer and a white polo are an easy way to introduce a hint of masculine elegance into your current casual repertoire. Don't know how to finish off? Add a pair of white canvas low top sneakers to your look to shake things up. During the winter months, when functionality is key, it can be easy to settle for a less-than-stylish look. This look, however, is a striking example that you can actually stay toasty and remain stylish in the winter months. As you're progressing through your late 20s, you probably want to start dressing like an adult. That's when outfits like this become a great source of inspiration.
