Rep. Jason Chaffetz (R-Utah) hasn't said if he'll run for the Senate next year but he has vowed to skip one of the upper chamber's annual traditions: Seersucker Thursday.

On a Thursday of every June, several senators wear the pale-blue-and-white-stripped suits, a tradition then-Sen. Trent Lott (R-Miss.) revived in 1996.

But Chaffetz, who's considering a primary bid against Sen. Orrin Hatch (R-Utah) next year, mocked the tradition on his twitter account Friday.

"Seersuckers may be dashing on others, but my pledge and promise is to never wear one," he wrote.

Then he added: "Wearing a seersucker suit is like wearing pajamas to work.... because they are."

ITK guesses that a lawmaker who sleeps on a cot in his office would know about wearing pajamas to work!
