The "Roar" singer sported a knit RVN crop top and matching skirt with a football motif on Thursday at the Super Bowl XLIX Halftime Show press conference.
Designer Ted Kim created the custom look just days before today's event.
"Let's just say I am dressed for the ball today… tune in on @nflnetwork #SB49," the 30-year-old beauty tweeted before the big event.
During the press conference, the pop star even poked fun at "deflate gate" -- the controversy about the New England Patriots allegedly using deflated balls in their playoff game against the Indianapolis Colts.
"I can assure you that nothing in my performance will be deflated," she joked.
Gotta love Katy's sense of humor!
Earlier this week, Perry showed off her newly-painted toenails, which featured football-inspired brown polish with a white cross-stitch pattern down the center of each one.
"Even my tippy toes are ready," she captioned the pic of her feet.
No word yet on if the pop star got a matching manicure ... but knowing Katy, she's going to have another outrageous sports-themed ensemble when she hits the stage on Sunday.
