I do not know if this is a normal look for the Michigan Basketball Band or if it was some sort of "dress like a superhero day." But, I seriously love this photo.
When I was in Basketball Band we wore blazers in a sort of medium blue color, with an embroidered maize M on one side. A little too dignified I think.
The photo is from the annarbor.com slide show about the Michigan vs Northwestern game in January.
