It's been a popular item in menswear for a while now, but the check shirt is now at its most ubiquitous. The question these days is, 'now everyone has one, what else can be done to elevate the look?' Perhaps you could take some inspiration from a French thief from the Sixties.
Jean Luc-Godard's impeccably stylish films have been the inspiration for generations of designers, but none more so than Band of Outsiders; there's even an entire clothing brand named after it. While it's packed full of style tips and dialogue that's influenced thousands of student directors, the main thing we took from it was Arthur (played by Claude Brasseur) and his great use of contrasting check patterns.
It's not exactly suitable to wear a heavy houndstooth wool coat in the middle of spring, so we've taken the contrasting checks idea and added it to this Nigel Cabourn Surface coat (End, £355) and an Our Legacy 1950's button down (End, £125). While it's a more difficult look to pull off, a general rule of thumb would be to keep the check patterns of contrasting sizes as well as colours. That way you won't look like an optical illusion.
