Suits are the modern man's armor. Some of us wear them everyday, while others only pull one on for special occasions. Whichever camp you're in, it's impossible to deny the "yeah!" feeling that comes from putting together a really decent formal outfit. But a suit doesn't have to be the preserve of work or formal dos.

ASOS personal stylist James Welsh (follow him on Twitter and Instagram for daily style advice) knows just how versatile your suit can be. "For me, the little details are what can make or break an outfit," says James. "If you're attending a formal occasion such as a wedding, try adding a tie bar to your outfit for an extra touch of class."
