Seattle's women's flat track roller derby league, Rat City Roller Derby, got its start in April 2004 as Rat City Rollergirls and quickly built a large local following. Rat City is a founding member of the Women's Flat Track Derby Association (WFTDA) and has achieved success on the WFTDA stage. The All-Stars team is comprised of the league’s best players and had a second-place finish in the 2007 WFTDA Championships. This uniform shirt was used by Flower Grosskopf under the name Dirty Little Secret when she played for the Rat City All-Stars team. Players compete using clever and funny fake names.
