Vera Wang Says Victoria Beckham's Wedding Dress 'Flew Back and Forth 4 Times on the Concorde' (Exclusive)

The former Spice Girls star's iconic dress featured a corseted bodice that traveled across the Atlantic for several fittings

In her more than three decades of designing wedding dresses for everyone from Gwen Stefani and Ariana Grande to Jessica Simpson and Kim Kardashian, Vera Wang has gone to extreme lengths to ensure each of her custom designs is a perfect fit.

And when it came to creating the champagne ball gown Victoria Beckham wore to tie the knot with husband David Beckham in 1999, that meant four flights between New York City and London. But Wang wasn't the one racking up all those frequent flier miles — it was the dress. Specifically its architectural sculpted bodice.

"I call it the transatlantic dress," Wang, 74, tells PEOPLE, while promoting her new Vera Wang LOVE campaign with Zales. "That bodice flew back and forth four times on the Concorde." She explains, "The actual under bodice was made by a very famous couture corsetiere named Mister Pearl, who works only out of London."

Wang says Mr. Pearl's corsets are designed to achieve an almost impossibly slim waist. (Mister Pearl famously created the corset in Kim Kardashian's custom "dripping wet" Thierry Mugler dress at the 2019 Met Gala.)

"He makes corsets that have to be pulled [in] with these metal things, which is how corsets were done in the old days," she explains. "It takes about 45 minutes to lace up, and it can take your waist down to literally 18 inches [like] Scarlett O'Hara."

She admits she finds that degree of cinching too extreme herself. "I could not live with that because I need to be comfortable, as I always say. But Victoria did."

Wang flew over to London to fit the corset portion of Victoria's dress on the former Spice Girl, and Victoria also came to New York twice for fittings.

When Victoria became pregnant with her and David's first child, son Brooklyn, the dress project was put on pause.

"So then we delayed the wedding for two years," Wang recalls. "Then we resumed, or maybe a year and a half. So that is [what] I call the transatlantic wedding with Victoria and David."

She even remembers a tiny Brooklyn, now 24, "crawling around on the bed in London" while his mom was doing her dress fittings.

In a fun throwback moment, Victoria re-wore her wedding dress, which featured a dramatic, 20-foot train, in a video for British Vogue in September 2018.

While the Vera Wang design remains one of the most iconic celebrity wedding gowns of all time, it wasn't the only dress Victoria wore on her wedding day. She and David, 48, famously showed up to their reception at Luttrellstown Castle outside Dublin wearing color-coordinated purple looks.

The former soccer star sported a double-breasted suit with a purple flower pinned to his lapel, and Victoria wore a mermaid-style dress with a colorful floral embellished strap. Baby Brooklyn even got in on the matching moment, wearing a purple suit, western hat and bib.

The couple poked fun at their regretful, "very '90s" fashion choices in the new Netflix docuseries Beckham.

"I tried to think back to when I decided to wear a purple suit. I don't know when that happened," David said, laughing sheepishly. "I think I just took Victoria's lead on it. But what… what were we thinking?"

Victoria — who has since built an eponymous fashion empire on her impeccable sense of style — defended the couple's very loud reception looks.

"But it was fun," she insisted. "We weren't worried about what people would say. I mean, Christ, how lovely to be that way when you just really don't care."

The Beckhams proved their style evolution when they stepped out to the London premiere of Beckham on Tuesday night. David looked dashing in a tailored navy blue suit and muted blue tie, while his wife wore a chic white double-breasted pant suit and black pumps.

The pair was joined at the event by all four of their children — in addition to Brooklyn, they share Romeo, 21, Cruz, 18, and Harper, 12 — and the siblings were just as stylishly turned out as their famous parents.

Harper even carried a purse from her mom's own brand, the Chain Pouch Bag, to accessorize her pale pink floor-length dress. Romeo, meanwhile, put a new spin on evening wear, sporting an oversized chocolate-brown wrap-style suit jacket and pleated, drop-crotch pants.

Beckham is streaming. now on Netflix.
