Katy Perry has once again amazed her fans and her supporters love it.
The American singer found her Firework Foundation in 2018, for which she is currently putting her archival concert looks up for auction.
For the charity campaign, the ROAR hit maker donned a red two-piece featuring a white polka dots series.
Notably, the top and the skirt were famously worn by her on July 7, 2009, at Capital Radio's Summertime Ball in London, during her early career shows.
The songstress surprised her fans as the long-time lovers were all very emotional, seeing the artist in the 17-year-old dress.
She also posted a carousel of images from the show, as one wrote, "This outfit and hair was everything."
It is to be noted that Katy wore the outfit, worth of $1,000 USD at her July 30th concert, which took place at Cardiff Castle in Wales.
For the unversed, the foundation, brought into existence by the chart-topper, is meant to be for the undeserved communities.
It was also previously revealed that it's mission is to serve the kids by providing them with access to the arts.
