Long before the invention of the air conditioner, seersucker legend says that Joseph G. Cannon, the House speaker, whose name now sits on the Cannon Building, broke dress code in the heat of summer and wore seersucker to meet with President Teddy Roosevelt, declaring it was “too damn hot” to wear the traditional wool suits worn year-round by his peers.
Mississippi Senator Trent Lott, long time adorner of seersucker, revived the Senate sartorial tradition by declaring the first Seersucker Thursday in June, 1996. His goal was to show that “the Senate isn’t just a bunch of dour folks wearing dark suits and - in the case of men - red or blue ties.”
In 2004, California Senator Dianne Feinstein encouraged female senators to participate in the tradition. In 2005, 11 of the 14 women senators attended Seersucker Thursday. Senator Feinstein served as National Seersucker Day co-chair along side Senator Bill Cassidy, M.D., until her passing in 2023.
In 2014, Bill Cassidy (R-LA), who at the time was a House member, called to have the seersucker tradition back, and again solicited the help of Senator Dianne Feinstein (D-CA) as co-chair. The proclamation he submitted to the Congressional Record designated “National Seersucker Day” and is celebrated each year on the second Thursday in June.
In 2024, Louisiana Senator Cassidy announced Senator Raphael Warnock as his new National Seersucker Day Co-Chair.
