(CNN) - Sen. Rand Paul's unconventional style in politics apparently extends to his wardrobe, as well.
The Kentucky Republican delivered a speech Wednesday morning while wearing a baseball uniform–white pants and all.

Paul spoke at the Leadership Institute just outside of Washington, D.C. at a 7:30 a.m. ET breakfast.
Wearing a red and white jersey with "Republicans" emblazoned across his chest, Paul had been practicing earlier in the morning for the upcoming Congressional Baseball Game for Charity.
He was also sporting a Western Kentucky University Hilltoppers hat. The university is based in Bowling Green, where Paul worked as an ophthalmologist before winning election to the Senate.
Paul later tweeted about his practice session, saying it was the GOP team's first meet-up before the June 25 game.
The potential presidential candidate has been known to dress down at times. During his speech at the Conservative Political Action Conference, for example, he wore jeans with his suit jacket and tie.
