Ah, to be Mr Harry Styles. Picture the scene: you’re in your swanky hotel room at the luxurious San Ysidro Ranch in California, chilling out before your agent’s wedding, and suddenly it’s time to go and take some “pre-ceremony photos”. But wait, you’re still in your fluffy white bathrobe! Do you change into a suit like everyone else? Do you buggery – you’re Mr Harry Styles. Instead, you wander out exactly as you are, picking up a glass of something strong on your way outside, and flash the camera with your winning grin. Everyone around you, including the bride and groom, is beaming with joy – and Twitter goes wild for the audacious sartorial move you’ve just pulled.

No, MR PORTER hasn’t taken to writing bizarre fanfiction – all of this actually happened last week, when Mr Styles made headlines for showing up to his agent Mr Jeff Azoff’s wedding in nothing more than a robe and slippers from the hotel spa. It’s a little unfair that whatever Mr Styles wears, people will applaud him for it, but such is his magnetism. If you or I went viral on Twitter for wearing a dressing gown and clutching a glass of whisky at a wedding, it would be because people were worried. Someone would probably start a Go Fund Me.

Mr Styles, who famously wears clothes with flippant and loveable panache, is not the first man to rock a dressing gown well, of course. The parallels he drew with a similar picture taken of Mr Jack Nicholson after he had just won at Cannes in 1974, cigar in hand, feet in pool, was uncanny (un-Cannes-y?). Indeed, there’s something about the caddish appeal of a successful man looking at ease in a clean white bath robe, free from the pressures of having to dress for anyone but himself.

Still, like all good things, the off-duty charm of a dressing gown can only ever be temporary. Traditionalists – and perhaps Mr Azoff – were relieved when Mr Styles cracked out a tux for the main event, this time accompanied by his girlfriend Ms Olivia Wilde, and they all lived happily ever after.

What Mr Styles will wear next we can only guess, but the man has certainly got range. And if anyone can give us an excuse to not feel guilty about staying in our pyjamas all day, well, we’ll take it.
