Jon Hamm knows his way around a suit. Or so says seven seasons of Mad Men. And like television's most affable cad, the 47-year-old knows how to lift a classic suit with a small, well-choosen detail.

At the world premiere of his latest show The Romanoffs, Hamm opted for Dunhill with a dual-striped tie. Rather than anything which reminds you of your school days, the design pares back on the pattern, hitting a happy midpoint between Ivy League and left-field.

The key takeaway here is simple. Like most things tailoring, match up your tones: so blue tie for blue suit, and a stripe that serves as both a complement and a contrast to the wider palette.
