A grey vertical striped long sleeve shirt and a white crew-neck t-shirt are the kind of a fail-safe casual getup that you so terribly need when you have no extra time to dress up. Our favorite of a countless number of ways to finish off this ensemble is with a pair of white leather low top sneakers. This getup is a surefire option if you're in search of a great, season-appropriate getup. And if we're talking casual fashion for 20-something gents, this outfit is a good look on almost any gentleman.
