Opt for a navy parka and black chinos for a fuss-free ensemble that's also put together. If you don't know how to finish, complement this ensemble with white leather low top sneakers. In the colder months, when warmth is prized, it can be easy to settle for a less-than-stylish outfit. This outfit, however, is a vivid example that you can actually stay comfy and remain equally stylish in the colder months. This combination demonstrates how to stay stylish as you go into your 30s.
