Lawyer and former model Alessandra de Osma was a stunning bride when she tied the knot to Prince Christian of Hanover this weekend, wearing a long-sleeved lace gown by Spanish fashion designer Jorge Vazquéz for her nuptials in Lima, Peru.

Perhaps what made her bridal look even more impressive was its similarities to another royal wedding dress: Kate Middleton's. Though the Duchess of Cambridge wore a custom Alexander McQueen design with a deep-V neckline when she wed Prince William in 2011, there are stark similarities between the two dresses.

Both dresses featured an opaque sweetheart bodice and sheer white lace on the chest and sleeves. De Osma's gown, however, featured a see-through overlay on the whole dress, while Middleton's lace detailing stopped at her hips and picked up again at the hem.

The dresses also boasted enormous trains, and both brides needed special assistance to keep them from dragging on the ground. Two women, including Prince Christian's half-sister Princess Alexandra, carried de Osma's train as her father escorted her to the church.

Kate's younger sister Pippa had her famous bridesmaid moment when she carried the bride's train while entering Westminster Abbey.

Their gowns were equally gorgeous from the back, too.

Then, there were the tiaras. De Osma donned the Hanover Floral Tiara, a headpiece with diamond-encrusted flowers and an heirloom of the House of Hanover. In recent history, it has previously been worn by Princess Caroline of Hanover (formerly Princess Caroline of Monaco) at a gala in 2004, and Ekaterina Malysheva (Prince Ernst August Jr. of Hanover's wife and de Osma's sister-in-law) at her own wedding last year.

Middleton wore a Cartier halo tiara, borrowed from the Queen, who first received the jewels on her 18th birthday, GoodHousekeeping.com reports. Although the piece lacked the height of the Hanoverian tiara, it still consisted of more than a thousand diamonds.

Like Middleton's dress, de Osma's bridal look also drew similarities to Grace Kelly's, which featured a high neckline and sheer lace detailing. The actress-turned-princess has close ties to the bride's in-laws: the late Kelly's daughter, Princess Caroline of Hanover, is the stepmother of de Osma's now-husband, Prince Christian. Princess Caroline wed Christian's father, Prince Ernst August of Hanover, in 1999, but the two are now estranged.

As we await the next royal wedding marked on our calendars—Prince Harry and Meghan Markle's on May 19—we wonder if the bride-to-be will also pay tribute to another famous royal with her dress of choice.
