This is an older commission done a bit over a year ago. 
Nonna from Girls und Panzer, wearing an Oarai school uniform as seen in the GuP movie... or not quite. The shirt and the skirt are both a little bit shorter than normal. Oh my, did she mix up uniforms with Katyusha? ;)
BTW, dear mods/admins, a Girls und Panzer category would be nice to have, given the show's substantial following ;)
