The "Modern Family" star mixed chic with sexy at Variety's Power of Young Hollywood event in Los Angeles, where the actress opted for an Alice + Olivia metallic stripe jacket and matching pair of pants ... while showing some major skin with a crop top underneath!
Our fashion panel -- including stylist Ali Levine and "Wrecked" star Jessica Lowe -- immediately took sides over Ariel's suit. While Ali loved that the starlet was more covered-up compared to the booty-baring ensemble she rocked days before, Jessica couldn't get on board with the "Beetlejuice"-approved duds.
And that wasn't the only time our panel disagreed!
Elle Fanning also walked the red carpet at the Variety event, sporting a whimsical Marc Jacobs gown. Though some of our experts felt the style was perfect for the young star, one of our panelists was not a fan of the "emoji dress."
And while Elle was all dressed up, Lady Gaga looked ready for bed in her pajama-inspired separates in New York City! The star recently called it quits with fiance Taylor Kinney and our panel couldn't help but speculate that her appearance was due to the split.
Either way, we still love you, Mother Monster!
