To normal people, the lives of Hollywood stars can seem so distant as to be entirely unrelatable. How many of us, after all, find ourselves posing for a bank of paparazzi photographers when we leave the house? How many have even set foot on a red carpet? When it comes to awards season, that annual circus of galas and gong ceremonies, our assigned role is to observe, not participate. The same goes for the who-wore-what fashion sideshow that precedes every big event: for all that we might feel engaged, we are not there; it is not happening to us.

When the closest we’ll ever get to attending the Oscars is following along with the live blog, it’s tempting to wonder what value, if any, we should place on what an actor thinks about getting red-carpet ready. And yet, listening to the collected thoughts of Mr Jeremy Irvine – an actor who has been on the red-carpet scene ever since his screen debut in 2011’s critically acclaimed, Oscar-nominated War Horse – it’s easy to be struck by the everyday usefulness of what he has to say.

Then again, perhaps we shouldn’t be quite so surprised. Eveningwear is perhaps the ultimate expression of classic style, the principles of which should, in theory, remain consistent regardless of whether you’re standing on the red carpet in front of the world’s cameras or just heading to a bar with a few close friends. A good suit is a good suit; and when it comes to traditional eveningwear, a Giorgio Armani suit might be the best suit of all.

MR PORTER’s exclusive, made-in-Italy eveningwear collection from Giorgio Armani, which features in our exclusive film with Mr Irvine, is a distillation of everything the brand does so very well. In its use of classic silhouettes and fabrics, there’s a sense of the old-world glamour we associate with red carpets of decades past, as exemplified by the roll call of screen legends to have worn the brand over the years, names such as Messrs Al Pacino, Leonardo DiCaprio, Denzel Washington and Robin Williams.

And in the occasional flourishes, such as the collection’s mulberry silk-satin shirt or mandarin-collar velvet tuxedo jacket, there’s an echo of Mr Giorgio Armani the iconoclast – the same designer who, in 1980, dismantled and rebuilt traditional tailoring from the ground up with his contributions to Mr Richard Gere’s wardrobe in American Gigolo.

Of course, the real secret to picture-perfect eveningwear is in the finer details. Compared to the extravagant, attention-grabbing gowns worn by the industry’s leading women (and, increasingly, some of the men) during awards season, men’s red-carpet attire can seem a little staid: the stereotypical “penguin suit”. It’s here that a Giorgio Armani tuxedo truly comes into its own, the sharpness of the cut and fineness of the fabrics elevating it above the ordinary.

Little wonder, then, that on the red carpet a Giorgio Armani tux has become a surefire sign that you’ve made it; indeed, no other designer has been worn by so many Best Actor Academy Award winners.

Off the red carpet, that same symbolism endures. “Being well-dressed is about confidence. A good suit makes me stand taller. It makes me feel like the best version of myself,” says Mr Irvine, expressing opinions to which any man can surely relate.
