While you might have been taught the four-in-hand knot the night before big-boy school for its time-saving simplicity, as you mature into worldly men, you ought to step up your tie-knot game. And it doesn’t get more big-boy than the Windsor knot. Learn how to tie it here

Firstly, the width of the tie bar you choose is always dictated by the width of your tie. This sounds simple enough, but getting it spot on will make all the difference. Wearing a narrow tie? Go for a short, half-inch bar. Wearing a standard tie? The half-inch will still work, but push it up a size for a more impactful look. As a non-negotiable rule, don’t ever let your tie clip go over three quarters of the tie’s width (or worse, hang over the edge).

"One of the big pocket square no-nos for me is when they directly match the tie, like they came together in a set,” says Dan Rookwood, US Editor at Mr Porter. “A pocket squareshould be used to add some interest in terms of colour and/or pattern.”

With this in mind, start by considering the rest of your outfit and then coordinate your accessories accordingly, without matching exactly. For example, a hint of burgundy in your pocket square’s print or pattern will team well with a burgundy tie.
