Is there any greater an authority on style today than Mr Tom Ford? The Texan-born designer is the very epitome of a well-dressed man, his eponymous brand the last word in modern elegance. When he exercises that famously smooth voice to wax lyrical on the topic of style, people listen.

What, though, does he have to say about those elements of an outfit that others rarely see? To mark the launch of TOM FORD Underwear, which is exclusively available online at MR PORTER this month, we asked Mr Ford to share his thoughts on this important, yet often invisible part of a man’s wardrobe.

Watch the film, above, to find out what he had to say.
