Katy Perry zipped into an all-black monochrome look for Balenciaga's show during Paris Fashion Week on Monday. The former "American Idol" judge joined celebrities and A-list guests like Ashley Graham and Nicole Kidman in the front row for the spring 2025 ready-to-wear collection.

Katy Perry fully embraced Balenciaga‘s out-of-the-box aesthetic at the brand's spring 2025 show on Sept. 30 in Paris, where the pop star and recent VMA honoree wore a dress resembling a suitcase with thigh-high pointed-toe boots.
