Complement your ensemble with white leather high top sneakers and the whole outfit will come together quite nicely. So if it's a baking hot summer day and you want to look dapper without exerting much effort, this look will do the job in seconds time. This ensemble proves how 20-year-old gentlemen succeed in the fashion department.
