This combo of a navy crew-neck sweater and navy chinos is very easy to imitate and so comfortable to sport over the course of the day as well! Our favorite of a myriad of ways to finish this ensemble is a pair of white and navy leather low top sneakers. When staying inside on a freezing winter day is not an option, this outfit just might get you through the day. Interested in outfit ideas for 30-something Millennial gentlemen? This outfit is pretty inspiring.
