For an ensemble that's very straightforward but can be styled in a great deal of different ways, consider wearing a navy double breasted blazer and burgundy chinos. Here's how to dress it up: derby shoes. So if it's a super hot warm weather day and you want to look on-trend without putting in too much work, this look will do the job in seconds time. A safe bet for gents in their 40s who are searching for age-appropriate looks.
