Great story, I noticed that the female students were wearing head-bands, I thought that only the men wore those.
Kryptonian women didn't wear headbands everyday like the males. However, on certain occasions they wore special headbands -- all Kandorians wore black headbands on the anniversary of Krypton's demise, for instance. That's why DC objected when the Supergirl movie producers wanted a headband for Kara's costume. This movie design ultimately became the "Crisis" outfit, and there were several panels in the Supergirl comic book where Kara justified her breaking of a wardrobe taboo. And then after all of DC's explanations, the movie producers decided on another costume for Helen Slater. :roll:
But note that these are female STUDENTS -- perhaps these headbands are used to assist the learning process by imparting information directly into the brain in conjunction with the ongoing lecture? We know Kryptonians also learned through similar mechanical means.
