This combination of a dark green wool suit and a light blue henley shirt is hard proof that a simple ensemble can still be seriously smart. Go off the beaten track and shake up your ensemble by rounding off with white canvas low top sneakers. Keep this getup ready to go when warmer days are here, and we promise you'll save time racking your brain for what to wear on more than one morning. If you frequently wonder how to dress as a 20-something, this combo is a good illustration.
