Trend Alert: Celebrity Cleavage Takes Center Stage (GALLERY)
Was there a memo that went around on Thursday night calling for cleavage-baring frocks? From New York City to Venice, Hollywood's leading ladies were dressed in sexy styles that highlighted their décolletage.
Kim Kardashian, 31, made a show-stopping entrance at Du Jour magazine's launch party on Wednesday night in New York City. Though the curvy star typically chooses styles that flaunt her derriere, last night, Kardashian showed off her other assets in a curve-hugging number with a cut-out neckline.
Also in Gotham City, Fashion Star host Nicole Richie, 31, sported a similar style to Kardashian for last night's 9th Annual Style Awards.
Rocking an extremely short Anthony Vaccarello black mini dress, Richie went all-out sexy, showing some major skin in a plunging cut-out neckline and sky-high heels.
What other stars dared to bare?
Pretty Little Liars' Ashley Benson flaunted her curves in a strapless sweetheart gown at the premiere of her new flick Spring Breakers at the Venice International Film Festival.
Benson, 22, looked sophisticated in her royal blue gown, but she wasn't the only young starlet to enter the Venice cleavage competition. Her co-stars Vanessa Hudgens, 23, and Selena Gomez, 20, also chose revealing necklines for the premiere.
Hudgens sparkled in a very low v-neck Alberta Ferretti gown alongside Gomez, who put her bust on display in a strapless custom-made Versace Atelier gown.
And rounding out the cleavage parade was diva Mariah Carey, who flaunted her assets while kicking off the NFL season in a short black halter dress.
