If I had to choose one, it would be the cargo trouser. Right now, it’s the ultimate blend of practicality and on-trend style, but this wasn’t always the case. Cargo pants broke out in the 90s, but there have also been times when they’ve been best left to middle-aged ramblers with hiking poles. Today, though, the ‘gorpcore’ revolution means hiking and outdoorsy gear is being worn in consciously stylish ways.

But cargo pants are not exclusively for adventure-inspired outfits. A pair with a slimmer, more flattering silhouette can also be worn with knitwear for a more considered and dressed-up look. Check out these from Brunello Cucinelli and OrSlow.

There’s so much conflicting advice on this topic, no wonder we have problems knowing what’s what. To solve them once and for all, I’ve devised this handy trouser colour matching matrix. For example, please note that it’s never acceptable to wear light brown or tan leather pointy shoes. With anything. Ever.

And remember that what makes or breaks a ‘Sometimes’ pairing is whether or not your shoes match the palette of your outerwear. Finally, make sure to match the colour of a belt with the corresponding shoe colour.
