Who: Timothée Chalamet

Where: 90th Annual Academy Awards, LA

On paper, all-white tailoring sounds all sorts of Vegas piano player. Yet Timothée Chalamet is as Timothée Chalamet does, and makes the trend wearable by subtly contrasting the shirt and tailoring. This guy is getting insufferable.

Who: Daniel Kaluuya

Where: Chanel And Charles Finch Pre-Oscar Dinner, LA

If all-white is a little too left-field for your tastes, do a Daniel Kaluuya instead. By subbing in a white shirt for black – and losing the tie – the Get Out star dials down both the statement and the formality for a stylish middle ground.

Who: Usher

Where: LA

Despite a recent split from the missus, Usher’s in no way veering towards a couch potato tracksuit or midlife crisis. The 39-year-old went for the statement jacket instead, pitting a wide colour palette against a backdrop of safer, quieter monochrome separates. She’ll rue the day she ever left.

Who: Jon Hamm

Where: 33rd Film Independent Spirit Awards, LA

Jon Hamm is Don Draper. Don Draper is Jon Hamm. And, if the 46-year-old ever complains about typecasting, may we refer him to this: a navy two-piece that’s quintessential Mad Men fodder, with a classic, glove-like fit overriding any volume or novelty.

Who: Gregg Sulkin

Where: Armani Pre-Oscar Party, LA

Superhero on-screen, sartorial saviour off it – Gregg Sulkin is giving Marvel’s old guard a run for its money. The Runaways star simplified an unusual koi carp print, embedding it within a fail-safe shell – the biker jacket – and anchoring with black denim and kicks below. Next stop: save the world.

Who: Chadwick Boseman

Where: Vanity Fair Oscar Party, Los Angeles

Another best-dressed line-up, another Black Panther star. Not that we’re bored. Chadwick Boseman shuffled his style once more, making two subtle pivots – a Mandarin collar and a longer, patterned jacket – without breaking the dress code. Your move, Michael B. Jordan.

Who: David Beckham

Where: New York

It wasn’t long ago that David Beckham looked like a dressed-up Kurt Cobain. He might have cut the hair off but he went grunge this week with wardrobe staples up-top, topped off with a parka. Beats a second-hand cardigan, anyway.

Who: Mark Ronson

Where: Vanity Fair Oscar Party, LA

Black tie needn’t mean a sea of penguin suits. As Mark Ronson proved, you can turn oil black to petrol blue, and still chime with the invitation. Simply ensure your jacket is of the dinner variety, and you’ll be the blue-chip dresser, too.

Who: Ansel Elgort

Where: Vanity Fair Oscar Party, LA

We’ve got a good feeling about Ansel Elgort. The Baby Driver gave us all the feels courtesy of a velvety dinner jacket for the red carpet. Follow the future style icon’s lead and you can add some much-needed texture and remain within the warm, safe embrace of the dress code.

Who: Shaun Ross

Where: Exclusive Forward by Elyse Walker Party, Paris

Despite gigs with McQueen and Givenchy, Shaun Ross is very much his (and his stylist’s) own man. An oversized overcoat is an easy way to refit your silhouette, and wider shoulders will flatter and complement added bulk up-top. Factor in well-fitting trousers and contrast kicks and we wouldn’t be surprised if Ross lands another campaign before the end of the week.
