The Most Expensive Red Carpet Dresses of All Time

Carrie Underwood lit up the 2013 Grammy Awards in a strapless black Roberto Cavalli gown that married sophistication with star power. The sleek mermaid silhouette and intricate lace detailing showcased Cavalli’s signature glamour, but it was the addition of her extraordinary jewelry that transformed this look into a multimillion-dollar spectacle.

The country star accessorized with a 380-karat diamond necklace valued at roughly $31 million, instantly making her one of the most dazzling figures in Grammy history. Underwood’s poise and understated elegance allowed the ensemble — and the diamonds — to shine without excess, perfectly balancing luxury and grace.
