Selena Gomez wore a gorgeous black-and-white Saint Laurent gown.

The dress features a flattering off-the-shoulder neckline and a column skirt.

Erin Walsh styled the look with Bulgari jewelry, which complemented Selena’s monochrome gown and enhanced her royal presence.

The Bulgari Swan necklace is a nice complement, combining transparent mother of pearl with brilliant-cut diamonds. It reportedly took 2,000 hours of meticulous craftsmanship to create the necklace, fashioned like a swan’s wings with a 20.08-carat drop diamond in the center.

Two Serpenti Viper rings adorned her red-manicured hands while a pair of long Le Magnifiche High Jewelry earrings dangled from her ears.
