Oscar Wilde famously said that ‘fashion is a form of ugliness so intolerable that we have to alter it every six months.’ Which is perhaps a little disconcerting, but one way of overcoming the constant yearning for sartorial satisfaction is buying well, buying clever and purchasing pieces of clothing that can mould to any mood and any occasion. And that’s a helpful rule of thumb that can be achieved by investing in an overshirt.

The simplicity of the overshirt – and its shirt-meets-jacket origins – makes it an ideal outer layer during the transition from autumn into winter, and even as a single layer when temperatures rise higher. Recently, the overshirt has been homespun by a number of brands – including A Day's March with the Trucker Brown Original Overshirt, and also by shirting-specialists Schnayderman’s, whose latest collection of stripped-back Swedish essentialism has just arrived online at OPUMO.

Schnayderman’s is a brand that has been built on an idea; that if you get the basics right and improve them with unique fabrics, then everything else will follow. Their Washed Black One Denim Overshirt, which anchors this edit, is evidence of this approach and is consequently one of the smartest overshirts that you can buy this season.

With its thick Japanese denim construction, patch utility pockets, and beautifully worn black hue, the One overshirt from Schnaydermans is tailor-made for fans of workwear. Which is why you can wear it with anything from heavy-duty denim to a pair of Diemme sneakers.

As the Schanyderman’s One Overshirt is designed to fade gently and gain character over time, it will give you all the hands-on kind of reliability you need to get through the day –coffee stains, beer stains, you know the normal kind of things. But best of all, the overshirt’s durability means it will look good in the process, and most importantly, it will look good on anyone; whether it is paired with dark denim, tailored trousers or chinos like the featured Stone Beige Dress Pant from Edwin. Worn untucked, the overshirt also functions as a practical lightweight jacket, when layered up over another shirt such as the Schanyderman’s Indigo Washed Japanese Denim Shirt. Or alternatively, it also functions as an insulating layer under a coat. Plus, you can unbutton it when hot or do it up when cold. Simple.
