Fashionable and practical, this laid-back pairing of a white long sleeve shirt and dark green chinos provides with amazing styling possibilities. Our favorite of a myriad of ways to finish off this getup is with mustard canvas low top sneakers. This outfit is a pretty savvy choice, especially for autumn, when the temperatures are dipping. Those wondering how to sport modern off-duty style in your early 20s, this ensemble should answer your question.
