Madonna is on the search for the vintage costume she wore during her surprise Coachella performance after it "went missing."

On Monday (April 20), the "I Feel So Free" singer took to her Instagram Stories with a plea for help finding several archival pieces of clothing that disappeared following her performance with Sabrina Carpenter at the 2026 Coachella Valley Music & Arts Festival on Friday, per People.

During her time on stage, Madonna told the crowd that her outfit — purple corset and lace-trimmed camisole with matching gloves paired with knee-high boots, stockings and Gucci jacket — was the same she wore while making her Coachella debut exactly 20 years prior. However, that makes the fact the pieces are missing even harder.

"This full circle moment hit different until I discovered that the vintage pieces that I wore went missing — my costume that was pulled from my personal archives — jacket, corset, dress and all other garments," she wrote on her Stories. "These aren't just clothes, they are part of my history. Other archival items from the same era went missing as well."

Madonna added that she is offering a reward for the "safe return" of the pieces, asking that "some kind soul" will find the items and reach out to her team via email at informaverick2026@gmail.com.

The Queen of Pop joined the "Espresso" hitmaker on stage for Carpenter's headlining set during weekend two of the annual festival, singing Madonna's hits "Vogue" and "Like a Prayer" as well as a track seemingly from her upcoming album Confessions II.
