Jessica Biel's Pink-and-White Wedding Dress: All the Details!

To cap off her nontraditional, week-long wedding extravaganza, Jessica Biel headed down the aisle October 19 in an equally nontraditional gown.

A source tells Us Weekly the Total Recall actress, 30, eschewed the standard all-white bridal ensemble, opting instead for a pink-and-white gown. After exchanging vows with Justin Timberlake, she changed into a less formal frock for the reception.

On Monday, stylist Bobbie Thomas took to her blog to share what she had learned about Biel's look: that the star had selected a Giamba! ttista Valli-designed dress with a "princess-like silhouette" for the ceremony, which took place at Italy's posh Borgo Egnazia hotel. (Thomas also reports that Biel's handsome groom, along with the male members of the wedding party, rocked Tom Ford suits.)

Biel's sartorial selection wasn't the wedding's only out-of-the-ordinary element; with the help of loved ones, Timberlake and Biel celebrated in Southern Italy not just this past weekend, but the entire week leading up to the ceremony.

As their big day drew closer, the pair did their best to keep their specific plans a surprise from friends and family, who didn't find out the location of the wedding until a few days beforehand. (Guests were first flown into Germany, and then finally via private jet to Italy.)

Says an insider close to the groom, "Justin wanted to be very slick with it!"

Timberlake brought his own unique touch to the reception, too. During the Friday evening soiree (which Questlove dee-jayed), the "Sexy Back" crooner served as his own wedding singer, serenading Biel with a never-before-heard song from his upcoming album.
