All About Blue, a retail store specializing in licensed University of Michigan apparel and novelties, was located at 307/309 S. State Street. It was popular with students, campus visitors and Michigan sports fans.

It was opened in September 2001 as Great Lakes Team Apparel by owner Bob Duerksen, who was hired by Steve and Barry's University Sportswear to open their first Ann Arbor location at 304 S. State in 1994 and oversaw their move to 303 S. State in 1996. In July 2008, the store name was changed to All About Blue when Duerksen arranged to lease the entire ground floor of the building.

All About Blue closed when The M Den purchased it from Duerksen on June 5, 2014.

All About Blue was a member of the State Street Area Association of merchants.
