Thursday June 12, marks National Seersucker Day, and Georgia Senator Raphael Warnock is helping lead the U.S. Senate’s recognition of the occasion as co-chair of the bipartisan celebration.

“Seersucker is more than just a fabric, it is a material deeply woven into Southern culture,” Warnock said in a statement.

Made popular in New Orleans in the early 1900s, seersucker is known for its lightweight, puckered texture and is traditionally made of cotton. The fabric gained popularity as a breathable alternative to wool suits during the warm summer months and has since become a style staple in Southern fashion.

The celebration also ties into Georgia’s agricultural identity; cotton is one of the state’s most important crops, supporting more than 50,000 jobs across the state in cotton-related industries.

National Seersucker Day honors the fabric’s deep ties to regional culture and its continued relevance in warm-weather wardrobes.
