It's a style showdown between a pop starlet and reality show vixen!
Ariana Grande turned heads at the Stand Up To Cancer telethon on Friday night, donning a white Mischa Collection lace bustier and pencil skirt during her performance. The "Break Free" singer completed the chic ensemble with white strappy stilettos and her signature high ponytail.
But, the 21-year-old beauty wasn't the only star to wear this fun frock!
Kim Kardashian put her curves on display in the same white two-piece during her 33rd birthday bash in Las Vegas last year. The "Keeping Up With the Kardashians" star paired the crop top and skirt with gold chained heels and an embellished clutch.
The craziest thing about Kim's take on the ensemble: She had just given birth to her first child three months earlier -- making her tight tummy and crazy cleavage something to talk about.
Both women looked fantastic in the designer duds, but who do you think wore it better? Tell toofab in the comment section below, and click "Launch Gallery" above to vote on more stars in dueling dresses.
