For functionality without the need to sacrifice on fashion, we like this combo of a grey turtleneck and brown chinos. You know how to tone it down: black leather low top sneakers. During the winter months, when warmth is key, it can be easy to settle for a less-than-stylish ensemble in the name of functionality. This ensemble, however, is a bright example that you can actually stay comfortable and remain equally stylish in the winter months. So if you need outfit ideas on what to wear in your early 20s, this outfit is ideal.
