Reach for a beige crew-neck sweater and chinos to achieve a seriously dapper and current off-duty ensemble. You could perhaps get a little creative in the shoe department and play down this look by finishing with white leather sandals. So if it's a roasting hot warm weather afternoon and you want to look sharp without exerting much effort, this outfit will do the job in no time flat. All in all, a good example of casual style for 30-something guys.
