A grey wool blazer and a navy turtleneck paired together are a sartorial dream for those who love effortlessly classic styles. Dark brown leather casual boots will pull the whole thing together. In the winter season, when warmth is imperative, it can be easy to settle for a less-than-stylish ensemble. But this ensemble is a bright example that you can actually stay snug and remain equally stylish during the winter season. So as you can see, in your mid-20s your dressing options are pretty much limitless.
