Taking the plunge at the CR Fashion Book Launch Party!

Givenchy by Riccardo Tisci ruled the red carpet at the CR Fashion Book Launch Party. The hottest celebrities wore some sexy, neckline dipping pieces at the party held in Paris, France.

Leave it to Kim Kardashian to jump on the latest trend – the plunging neckline. The reality TV diva aka Mrs. West wore an extra low-cut black Givenchy jumpsuit that put her well-known figure on parade. Kim wore a black grain-de-poudre tuxedo with satin details worn with black pleated jersey bodysuit, oversized crystals and pearls brooch and black velvet sandals.

There is no denying that Kendall Jenner has won the hearts of many during fashion week and has taken the world by storm. Love her or hate her, she is definitely here to stay. The blossoming supermodel looked sophisticated in a plunging black jumpsuit in cady and satin, worn with black and gold suede leather sandals.

Joan Smalls took the plunge as well in this bold ensemble, and coming off the tail of a successful fashion week, the supermodel stunned in a black gown with a deep neckline and sheer top. Smalls wore a black dress in satin, tulle and lace worn with suede leather sandals.

Ciara looked fierce on the red carpet in a sheer black plunging Givenchy gown at the launch party. The singer appeared calm and collected after being ambushed earlier in the day by Ukrainian prankster Vitalii Sediuk on her way into a fashion show. Ciara wore a Givenchy by Riccardo Tisci Spring Summer 2015 black lace and chiffon evening dress, worn with a black crystals necklace and thigh high nappa leather boots with laced front.
