All eyes were on Meghan Markle Saturday as she walked down the aisle — and finally revealed her dress — at her internationally anticipated wedding to Prince Harry in Windsor, England.

The 36-year-old American actress paired a Givenchy gown with a tiara from Queen Elizabeth and a 16-foot veil detailed with flowers from all 53 countries in the British Commonwealth.

While using Givenchy, a French fashion house, was unexpected, Clare Waight Keller designed Markle’s wedding dress. The British designer was Givenchy’s first female artistic director last year, Kensington Palace announced.

Markle’s dress featured an open bateau neckline and a triple silk organza underskirt, according to Kensington Palace. And though no price has been publicly released, we do have an idea about how much custom Givenchy dresses cost: When Kim Kardashian wore one at her 2014 wedding to Kanye West, it was valued at $500,000.

Samantha Brown, a New York-based celebrity stylist, tells MONEY that although the dress may initially appear simple, the fabric and tailoring likely drove the cost up.

“The gown is exquisite in its fit, and the fabric drapes perfectly,” she says. “While it isn’t beaded or embellished, two components that always signify ‘expensive,’ the attention to detail and, of course, Givenchy price tag surely make this gown extremely lux.”

Dawn Del Russo, a fashion expert and founder of Bella Dawn, says Markle’s wedding dress has an “absolutely American princess feel.”

The ceremony caps off weeks of speculation about who would design Markle’s wedding dress, what it would look like and how much it would cost. Many of the rumors were linked to a comment Markle made about her favorite wedding gown of all time: the one Carolyn Bessette Kennedy wore at her 1996 ceremony, a slip dress the New York Times that was about $40,000 back then. Others were inspired by her Suits character, Rachel Zane. When Markle-as-Zane got married on TV, she wore a $6,800 Anne Barge creation in the Versailles style.

Similarly, the wedding dress Markle’s sister-in-law — Catherine, the Duchess of Cambridge — wore when she wed Prince William in 2011 was also fiercely debated. Catherine, the Duchess of Cambridge’s wedding dress was the subject of much debate when she wed Prince William back in 2011. Whereas royals aficionado Katie Nicholl told Entertainment Tonight this past March that Kate’s parents paid £150,000 — about $203,000 — for the dress, the Daily Mail reported at the time that it cost £250,000 — about $338,000.

However, Nicholl did predict that Markle would avoid outdoing her sister-in-law.

“I think it was very unlikely that Meghan would spend more than that, and in doing so try and upstage a future queen,” she told ET.

But Markle didn’t have to worry about exceeding the budget of her late mother-in-law, Princess Diana. According to CBS News, Diana’s dress cost just $13,000. And Queen Elizabeth II paid for hers with coupons.
