Seersucker Thursday was an annual tradition in the United States Congress in which Senators don the lightweight, striped, summer-friendly fabric seersucker, in the spirit of traditional Southern clothes, on usually the second or third Thursday of June.[1]
The tradition was started by Republican Senator Trent Lott of Mississippi in 1996 who wanted to ""bring a little Southern charm to the Capitol"" to remind the Senate of how Senators dressed before the advent of air conditioning in the 1950s.[2] The cotton weave, which originated in western India, became a signature look of the United States in the early 20th century because its light weight and pre-rumpled surface made it ideal for the oppressive humidity of summer.

While this tradition was an annual event, it is common to see Congressional staffers don seersucker suits on Thursdays throughout the year.
