The fashion industry isn't exactly known for prioritising comfort and ease when it comes to dressing, so when a rare trend comes along that places both of these front and centre, you can bet we're going to instantly pay attention. Introducing the fashion girlie's favourite 'fit of the moment and your new go-to simple summer dressing hack: ‘dayjamas’.

And yep, it's exactly what it sounds like – pyjamas designed to be worn during the day. A dream come true, right? But trust me: you'll want to keep your *actual* PJs at home, and invest in a more elevated co-ord that's less sleepwear and more street style-friendly instead. Think: breezy linens, luxe silks, bold colours and elegant patterns that are too good to be hidden at home – and importantly, always with an effortlessly chic relaxed, breezy fit.

Brands like Lone Star Daughters, With Nothing Underneath, Toteme and Alémais are currently leading the way with their stylish takes on dayjamas that already have countless famous fans, while those who have already seen The Devil Wears Prada 2 will know that even Nigel Kipling (aka Stanley Tucci) is a firm proponent of the trend. And that is the ultimate seal of approval, IMO.

Luckily, the trend has also trickled down to our favourite high-street shops, where you can get the look for less. In fact, M&S's striped shirt and trouser dayjamas set is one of the best out there – and so easy-to-wear that it just might replace your usual summer dress for good. Not only does it feature a drawstring waist, lightweight fabric and slouchy fit, but the chic stripes design and mother-of-pearl-effect buttons make it look so much more expensive than it is. We're sold!
