Hailey Bieber Does Audrey Hepburn at The Tiffany Landmark

The model did her best ‘Breakfast at Tiffany’s’ impression at the opening of The Tiffany Landmark in NYC.

What do you wear to the opening party of the newly renovated Tiffany & Co. flagship, The Landmark? One would assume diamonds — after all, they are a girl’s best friend and the jeweller’s best seller. But not if you’re Hailey Bieber.

After three years of a daringly ambitious renovation — the first since it opened its doors in 1940 — the Tiffany & Co. Fifth Avenue store finally reopened its historic doors and the stars celebrated in style. Like a modern Holly Golightly à la Breakfast at Tiffany’s, Bieber wore a Versace LBD with strands of pearls and a Tiffany Blue manicure. She spent most of the night with the equally effervescent Zoë Kravitz, who paid homage to Tiffany’s former designer Elsa Peretti by wearing a halter top with a silk Saint Laurent button-down and pencil skirt.

Blake Lively, Anya Taylor-Joy, Brooklyn Beckham, Nicola Peltz, Michael B. Jordan, Jacob Elordi, Gal Gadot and others were also there (along with FASHION, by the way). Still, Florence Pugh caused gasps to ripple in the fashionable crowd. Debuting new bangs and a bob, the actor looked like she was carrying a wind machine the whole night as her mint green Valentino gown danced wherever she went. And as this is Tiffany & Co., having a crowd full of stunning A-list stars simply wasn’t enough. The brand surprised everyone with an intimate performance by Katy Perry that ended with iridescent confetti covering the partygoers.

But the true star of the night was the venue itself (sorry Mrs. Biebs!). While the party was so packed I could barely see my bedazzled green pumps, I luckily got a private tour of the premises the day before. Now, at first glance, the reveal is admittedly a little anticlimactic: the storefront’s iconic limestone, Atlas Statue and clock remain relatively unchanged. However, the new three-story glass addition, spearheaded by the Office for Metropolitan Architecture (OMA), gives a glimpse into the innovation you can expect from the interior by legendary architect Peter Marino.

Entering through the grandiose revolving doors, the first word that comes to mind is luxury. In case the location (57th Street and Fifth Avenue) wasn’t enough of an indicator that you are walking on NYC sidewalk royalty, the ground floor features a giant LED screen that mimics windows, with views of the Manhattan skyline and Central Park. The walls that aren’t covered in pixels are adorned with art by renowned artists like Damien Hirst, and the entire space glitters and glows as if it were dunked in the bubbliest and sparkliest Champagne imaginable.

But be warned — the Tiffany Landmark is massive, so much so that I recommend sporting a pair of sneakers if you want to make it to all ten floors in one piece. However, if you’re willing and able to take the stairs, I highly suggest you do. Before you protest, this is no ordinary staircase. Inspired by the aforementioned Peretti’s love of organic forms, the steps are surrounded by rock crystal columns and angled infinity mirrors, which are guaranteed to take your mirror selfies to the next level (pun intended). Head to the seventh floor to check out the most extensive collection of Tiffany high jewellery in the world, with the crown jewel of them all — a strand of perfect pearls valued at $2.8 million that is so elegant and understated, it’s begging to be worn by Hailey Bieber at this year’s Met Gala.

If seeing all the delicious jewellery has made you feel a bit peckish, the Instagrammable Blue Box Café has reopened and will have you seeing Tiffany Blue long after your amuse-bouche. “The Audrey Experience,” a mini shrine to Hepburn and the iconic movie, complete with a replica of the LBD and pearl necklace from Breakfast at Tiffany’s  is on floor five. The famous 128.54-carat Tiffany Diamond has been redesigned and is currently on display in the window. And, if you can maneuver your way onto the guest list, there’s even a secret club on the top floor with its own elevator. Consider it Hailey Bieber- and Holly Golightly-approved.
