Katy Perry's outfit at One Love Manchester concert had one emotional detail you might've missed

Katy Perry rocked a fashionable white ensemble at Sunday's One Love Manchester benefit concert, but there's one detail about her outfit that you may have missed.

At some point during her two-song set of "Part of Me" and "Roar," Perry took off her massive white fur coat to reveal a collage shirt underneath her white dress -- and on the shirt were images of the 22 victims of the devastating Manchester bombing.

The victims, including super fans Martyn Hett and 18-year-old Georgina Callander, were featured on the garment, though they were a bit difficult to make out while Perry was performing.

"It's not easy to always choose love, is it, especially in moments like these, right?" she asked the crowd at one point. "It can be the most difficult thing to do. But love conquers fear and love conquers hate. And this love that you choose will give you strength, and it's our greatest power."

The thoughtful tribute by Perry was just one of the many emotional aspects of Sunday night's show, which also featured performances from Ariana Grande, Miley Cyrus, Niall Horan, Coldplay, Robbie Williams, Little Mix and more A-list stars.

One Love Manchester raised over $2.6 million for the families of the Manchester bombing victims during the 3-hour show on Sunday night.
