An impromptu snooker match, an Eighties boyband-themed surprise party; there are many reasons why it could be useful to have a waistcoat secreted about your person at all times.
Which is probably why the good folks at Missoni and London retailer Jean Machine have created the JM4 jacket (£340, right): a devilishly dapper denim number, with a detachable zigzag felted wool waistcoat hidden underneath.
This piece is part of Jean Machine’s new autumn/winter range, which sees the brand – which previously ruled the denim roost on London’s Kings Road back in the Seventies – relaunching in style by partnering with iconic Italian fashion house Missoni to create a new capsule collection for modern men.
The JM4 aside, we’re also particularly keen on the straight-leg jeans (£190), in clean blue-rinse wash, with knitted pockets. For keeping your keys warm, presumably.
