The perfect summer jacket can transform an otherwise-lacking look instantly, allowing you to level up your whole fit with the pop of a button or the zip of a zip. To me, the jacket is the most important part of the wardrobe; an investment item to base everything else you wear around for seasons to come.

Of course, it is warm outside, so said jacket needs to be lightweight. Fabrics like nylon or polyester work well, especially when facing downpours. In the cool of the evening, though, you can afford to turn to the more heavyweight likes of denim or cotton. We hit the internet to bring you a selection of the season's best.
