At least, it does if you leave boxy shapes to Gordon Gekko. “Find a jacket which is tailored shorter in the body and with broad peak lapels to give you the most flattering fit,” says Arnold. “The double-breasted blazer should accentuate the chest and slim down the waist, to give you a sharper silhouette.” But learn the difference between fitted and skintight. “Otherwise it will pull and look messy.”

And while ideally you’d own a clutch of double-breasted blazers to suit wherever you end up this summer, the utility DB is so adaptable that, really, you only need one. So long as the colour is as versatile as the style. “Go for lighter, neutral shades of beige, khaki, or stone,” says Farnham. Blue is another safe option, but consider lightening up. “Try a chambray-style cotton as opposed to that City boy-style dark navy. And at all costs avoid black. It sucks up heat and will be unbearable.”

5 New Ways To Wear The DB This Season

Double-Breasted Jacket + Chinos + Knitted Tie

There’s a time and place for the double-breasted suit, and it’s not when the pavements are melting. If client meetings mean you can’t go full Friday casual then ditch the matching trousers and step into lightweight cotton chinos.

These mismatched separates offer double benefits; your pins stay cool and your look stays the right side of stuffy. A neutral jacket can be teamed with any shade of strides, but to ensure top and toe mesh, reflect your trousers’ tone in your tie’s recessive colour. It’s business wear with added breeziness.

Stenstrom SS16

Double-Breasted Jacket + Air Tie + Lightwash Denim

A blazer and jeans is the smart-casual default, a proven pairing in the sweet spot between night and day, office and bar. Hence why that bar’s flocked with guys all dressed the same, in navy jackets and darker denim.
