#10: Lady Gaga in Valentino
Cost: $198,846
At the 2019 Golden Globes, Lady Gaga delivered a fairytale moment in a voluminous periwinkle Valentino Haute Couture gown. With cascading layers of silk and an impossibly long train, the design nodded to Judy Garland’s A Star Is Born era. Its delicate hue and sculptural drama were pure Valentino magic.

Gaga completed the look with a matching Tiffany & Co. diamond necklace and hair dyed to echo the gown’s icy tone. The monochromatic styling amplified the visual impact, while her poise channeled vintage Hollywood royalty. It became one of the most talked-about and instantly iconic red-carpet looks of the decade.
