Sánchez wore a golden off-the-shoulder duchess satin dress for the occasion.

The look — part of Schiaparelli’s Spring-Summer 2025 Haute Couture collection — featured a corseted waist and baroque floral embroidery that called to mind the city’s famous carnival masks.

She styled her hair in a high ponytail with face-framing pieces in the front.

Bezos sported a classic black suit, which he paired with a crisp white dress shirt and aviator shades.

The couple’s celebrity guests were spotted making their way into boats en route to the soirée including Orlando Bloom, who wore a cream dress shirt and tan slacks; Tom Brady, who sported a white shirt and black pants and had a tan jacket slung over his arm; Kris Jenner and Corey Gamble in coordinating black looks; and Kim Kardashian, who made a statement in a form-fitting, snakeprint dress.

Kendall Jenner, wore a colorful floral dress, while Kylie Jenner, opted for a gold lace strapless look.

A source tells PEOPLE the guests arrived in a convoy of about 30 boats. Amid security concerns, police patrolled the area, including the water on jet skis.

An entire canal was blocked up with boats dropping guests off at the venue.

The soon-to-be bride and groom were among the last to arrive, and security created a cordon around the couple to shield them from onlookers.

Another source tells PEOPLE the couple and their guests will be eating pizza cooked onsite by a famous Neapolitan chef.

Over the course of the day, baskets of white and purple-colored flowers were brought in to decorate the venue, along with a piano.

According to the insider, the atmosphere was surprisingly low-key considering the high-profile guest list.

DiCaprio is a longtime friend of Bezos and Sánchez.

In 2023, DiCaprio and Bezos jointly supported the Protecting Our Planet Challenge, Bezos’ $10 billion fund, to help protect the Amazon rainforest, its wildlife and the indigenous people who live there.

The pair pledged to help the organization invest $200 million into the Brazilian government’s conservation efforts until 2027.
