Stepping out for their first red carpet as a married couple, a beaming Miley Cyrus and Liam Hemsworth showed the older folk how to rock it at the Los Angeles world premiere of Avengers: Endgame.

The crowd for 2019’s most anticipated movie launch was heavy on A-listers – Matt Damon, Brie Larson, Robert Downey Jr – and pretty big on style too.

Some of it was boring, some was bang on and some was quite fabulously bad.

Miley (with new hair) and Liam won best dressed by a mile, thanks to their glamorous, polished old Hollywood twinning.

Both in St Laurent, her dress was perfection – that neck cutout made it worthy of being a piece of art in Don Draper’s apartment – and his tieless tux was sharply classic.

Another Hemsworth, Chris, and his wife Elsa Pataky had their own look going, with mixed results. Like Miley, the Spanish actor went retro in a white halter gown and red lip, while Thor was budget Davy Jones in paisley (that’s not a typo.)

In a tricky length bodycon metallic dress, Scarlett Johansson looked like a fleet car: Not top dollar and goes alright but doesn’t excite. Her date, comedian Colin Jost, appeared to know it.

In silk Celine, Brie Larson looked like Scarlett should have. Amazing colour, perfect length and cool rather than cliched.

Gwyneth Paltrow wore a skivvy with a man’s dinner jacket and current Hollywood favourite, the invisible sandal. She looked thrilled, which ultimately is all that matters. Cautious tick.

Katherine Schwarzenegger and Chris Pratt looked ace, even if he was wearing a too-tight funeral suit. I’m not even looking at her Grecian animal print number and 1998 newsreader hair, just their happy faces.

Josh Brolin and Kathryn Boyd (her GHD curls put Schwarzenegger’s in the shade) had a Mom and Pop Dress Up to Go Out night. Honey, why don’t you wear those pyjamas you got in Ho Chi Minh? Sure honey, but only if you wear the suit we bought in case you ever need to go to court.

Karen Gillan smashed it. Check out her mismatched shoe bows. Original, fun, sexy.

Linda Cardellini treats every red carpet like a costume party and this time she came as a knowing showgirl about to cash in her chips and open a bar in Cancun. Awful and terrific.

Lydia Hearst looked a bit like an exotic bird that has flown into a plane engine. Great shoes.

Letitia Wright was sleek and sophisticated, like a ladylike fembot in a good way. Accessories could have done with more personality.

As ever, Robert Downey Jr nailed the arty intellectual look – every man now should be running out to buy a pale mango shirt, bug glasses and double-breasted suit – while wife Susan went the urban reptile path.

Natalie Portman was most acceptable in a high-necked look with printed skirt reminiscent of what you’d wear if you wanted to slay at a dressy Hawaiian cruise luau.

Evangeline Lilly’s insouciance is the key here. Karen Gillan and sports teams aside, black and red is a nightmare to pull off but the loose draping is quite beautiful.

Are Mark Ruffalo and Sunrise Coigney the most fantastic couple in any room? Her long shag cut is world’s best practice, she’s super sexy in flats and without showing an inch of flesh and has a man in a deep mulberry suit on her arm.

Laurence FIshburne is so his own man! Or is he someone else, like one of those fake monks who haunt city train stations? In stolen shoes?

Danai Gurira chose girly lollipop pink which somehow looked perfect during awards season but now is a tiny bit naff in an indefinable way.

Zoe Saldana’s fuchsia was so, so much better: Interesting, architectural and unexpected. That handkerchief hem is tragic though.

After the show, Bradley Cooper was racing off for a job interview with a merchant banking firm.

Tessa Thompson took a brilliant risk in structured, contemporary black with statement motifs. Love it. Love her confidence.

Vin Diesel was as pumped as anyone pioneering a jacket made of rock face and lichen should be.

Elizabeth Olsen’s plunging faux wrap dress was like its wearer: A total standout in an understated way.
