Grandad Collar Shirts

In the old days, shirts used to have removable collars so they could be worn multiple days of the week. You’d swap the collar out to keep it fresh. With the collar removed you’d essentially be left with a smarter version of what is today known as a grandad collar shirt.

Because they lack collars, grandad shirts are inherently less formal than their collared brethrens and are therefore better suited for summer. They work best when the top two buttons are left open, the sleeves are rolled up and they’re left untucked. Find one in a cotton or linen mix and wear it to a rooftop bar or pub garden to reap the benefits.

In terms of pairing it with other garments, think ‘casually tailored’. A pair of relaxed chinos or trousers with either a cropped or rolled hem is a perfect accompaniment, as are some crisp sneakers – minimal or vintage runners.

Open Collar Shirts

The open collar shirt is the classy way to show off the pecs this summer without resorting to that staple of trashy reality TV, the V-neck tee.

With more names than a secret agent – you can call it a Cuban, camp or revere collar if you like, its all the same – the main criteria to scout for is mini lapels that lie flat against your chest, a cut beyond your waistband so there’s the potential to tuck it in and a floaty material (poplin cotton or viscose work best).

Block colours are easier to style, but the open collar is a versatile beast and a bulldozing print will bowl onlookers over when popped under a navy or black blazer. Alternatively, wear with a white vest underneath for a summer look straight out of the Hollywood playbook.

Knitted Button-Through Polo Shirt

Despite being a default option, the pique polo shirt doesn’t earn its spot alongside real summer classics such as the Oxford shirt or the grandad collar. This is due in large part to the fact that it’s been co-opted by stag parties, middle-aged manspreaders and every other undesirable style icon imaginable, ad finitum.
