If you thought getting into Fort Knox was tricky, try the Victoria’s Secret Fashion show. Layers of security guards with sniffer dogs, banks of clipboard-wielding PRs and at least seven ‘ticket please Ma’am’ ushers had to be navigated before you could claim your seat in the cavernous Armory show venue in Manhattan on Tuesday night.

But the security fandango was all worth it, of course. After an away match in London last year, the ‘Super Bowl of fashion shows’ was back on home turf to celebrate its 20th anniversary in suitably splashy style.

On the silver runway familiar faces from the veteran Victoria’s Secret ranks – including Lily Aldridge (who this year wore the diamond-covered $2 million Fantasy Bra), Candice Swanepoel and Adriana Lima – were joined by stylish new blood in the shape of Gigi Hadid and Kendall Jenner.

What do the Angels REALLY eat before a show? This is what a Victoria's Secret model diet looks like...

But before the show even began another media frenzy was well under way after Kris and Caitlyn Jenner both showed up in cocktail dresses and had a conspicuous hug and catch-up on the front row – a very public show of unity after rumours of fighting in the Kardashian-Jenner clan.

Rihanna had originally been billed to perform alongside The Weeknd and Selena Gomez, but was replaced by Ellie Goulding after pulling out just a few weeks ago.

In the end it was Ellie who delivered one of the highlights of the night: a beautiful rendition of Love Me Like You Do in front of a huge white wooden façade, under a shower of fake snow.

As ever with a Victoria’s Secret show, the looks were cheerfully ridiculous, featuring giant American flags, surf boards, rotating wheels of feathers and even LED fireworks.

And unlike other fashion shows, the models smiled, waved, high fived each other and blew kisses into the crowd. The positive atmosphere was infectious. By the end of the show everyone (including us) was on their feet.
