On Monday, Brazil Mayor Ann Bradshaw signed a proclamation encouraging members of the local union to wear pink.
Union President Jake Bennett said firefighters will wear the "Passionately Pink" T-shirts on Thursdays and Fridays through October.
In addition, city hall associates will be allowed to wear the shirts on those days as well.
Bennett said the union recently passed a resolution recently in order to help create more awareness regarding breast cancer.
The International Association of Firefighters also teamed up with the Susan G. Komen Foundation, which supplied the T-shirts.
Bennett added county residents may purchase the T-shirts for $12 by calling him at 812-236-7354.
"Any funds raised go to the Susan G. Komen Foundation Passionately Pink program," Bennett said.
