Paris Hilton's Shimmering Gown with a Plunging Neckline Wins Best Dressed Wedding Guest.

In addition to flowers blooming and the arrival of warmer weather, spring also marks the start of the wedding season.

Allow Paris Hilton's most recent look to serve as inspiration if you're struggling to come up with a standout wedding guest outfit.

The mogul was one of the famous guests at Sofia Richie and Elliot Grainge's lavish wedding in the French Riviera last weekend.

Hilton dazzled on the day of the event with a stunning icy blue gown. All over the long-sleeved dress,

radiating from a collected center, were glistening, light blue sequins. The dress also featured a deep V-neckline that was embellished with sparkling...

...crystals to match Hilton's diamond choker necklace and diamond stud earrings.

She added two more pieces of jewelry: a white pair of sunglasses, and a silver dazzling clutch.

Carter Reum, who was also in several images, looked dapper in a traditional black tuxedo with a white dress shirt and a black bowtie.
