Princess Meghan Markle arrives at St. George's Chapel at Windsor Castle for her wedding to Prince Harry

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.

“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.” “Haute couture gowns like this can be priced as high as $340,000,” she adds. “Safe to say her couture designer gown that will be marked in history is in the hundreds of thousands.”
