Katy Perry added a unique touch to her look for the One Love Manchester Benefit concert on Sunday.

The 32-year-old donned a white, long-sleeve Sonia Rykiel dress adorned with photos of the victims of the May 22 Manchester attack at Ariana Grande’s concert, which killed 22 people and left dozens more injured.

The photos covered her collar and wrists, but most noticeably, formed the shape of a heart that draped across her back.

But more than just the powerful message she rocked in her look, Katy delivered a powerful performance to go along with it.

She took the stage and gave a short speech, saying, “It’s not easy to always choose love, is it? Especially in moments like these, right? But love conquers fear, and love conquers hate, and this love that you choose will give you strength. It’s our greatest power.”

The singer then performed an acoustic version of her 2010 hit “Part of Me” and followed it up with her big anthem “Roar.”
