10 Years Later: All the Details From Tom Cruise and Katie Holmes' Lavish Italian Wedding

"I think every little girl dreams about [her wedding]," Katie Holmes said in an interview with Seventeen in 2004. "I used to think I was going to marry Tom Cruise."

"So let it be written, so let it be done."

As fate would have it, her childhood wishes came true less than a year later when, newly split from fiancé Chris Klein, she accepted the Oscar winner's marriage proposal, subsequently gave birth to the couple's only child, Suri, and went on to marry her girlhood crush in one of the most significant wedding ceremonies in Hollywood history.

As pop culture history goes, the marriage ended in a divorce settlement five and a half years later with primary legal custody of Suri granted to her mother.

Nevertheless, for nostalgia's sake, today marks a different milestone for those vows—their 10-year anniversary. On this day in 2006, the actors became husband and wife inside Bracciano, Italy's 15th-century Odescalchi Castle, a celebration that reportedly cost them upwards of $3 million. 

With a price tag that grand, Tom and Katie's wedding cemented itself in celebrity bridal history. From the cream of the crop Hollywood guest list and double wedding gowns to a dinner serenade by Andrea Bocelli, it seems no expense was spared on the night Holmes became Mrs. Tom Cruise. 

"If you get invited to that wedding, you go," Brooke Shields, a guest at the wedding, told Jenny McCarthyin an interview on her SiriusXM show in January.  

Before the wedding could begin, the bride needed a gown—or two. Holmes sported two dresses during the special night, both designed by wedding attendee Giorgio Armani. For the ceremony, the Ray Donovan actress donned an off-the-shoulder silk and lace design adorned with Swarovski crystals. The crystals alone took 350 hours to place, as People reported at the time.

Then, she switched into a one-shoulder off-white silk organza number embellished with more Swarovski crystals.
