Kylie Jenner Defies Wedding Guest Dress Code In Silver Gown At Jeff Bezos And Lauren Sánchez's...

Kylie Jenner is pushing the boundaries of wedding guest dress codes for the nuptials of Lauren Sánchez and Jeff Bezos .

For the Friday June 27, celebration, the Kylie Cosmetics founder, 27, appeared in a silvery blue corset gown that was dangerously close to white. The ensemble featured subtle cutouts under the bust, tiny black bows on the straps and a lace-up detail running down the length of the dress.

Kylie's hair was pulled into an updo and she accessorized with 33-carat Lorraine Schwartz studs and a 25-carat Lorraine Schwartz diamond ring and sunglasses.

Kendall, meanwhile, opted for a black gown and scarf. She added a Lorraine Schwartz necklace of 110 carats of Colombian emeralds with a 65-carat pear-shaped drop and earrings that were 70-carat pear-shaped drops. The model, 29, wore her hair in a tousled updo with face-framing pieces left out.

The day before the nuptials, Kylie and Kendall attended the couple's welcome party alongside sisters Kim and Khloé Kardashian and mom Kris Jenner, who brought along Corey Gamble as her date.

Each Jenner channeled romantic Riviera style in their own way, with Kylie going for a sexy sheer lace dress and Kendall opting for a summery floral halter dress.

Meanwhile, Khloé and Kim went even more daring . Tthe Good American founder glammed up in a gray dress with cutouts and the SKIMS mogul turned heads in a snakeskin bodycon. Momager Kris chose a black dress with a low neckline.

A source tells PEOPLE the couple has made some last-minute changes ahead of their wedding, in light of ongoing protests that have cropped up across Venice, with posters, stickers and signs around the canal city's historic center reading "No Space for Bezos."
