This pairing of a charcoal parka and skinny jeans is on the casual side yet it's also dapper and extra sharp. When it comes to shoes, go for something on the more elegant end of the spectrum by slipping into a pair of low top sneakers. In the winter season, when practicality is imperative, it can be easy to settle for a less-than-stylish outfit. But this outfit is a clear example that you can actually stay cozy and remain equally stylish in the winter season. This getup illustrates that heading into your 30s is no reason to shed casual style altogether.
