CLAMP School Defenders is one of my absolute favorite mangas (CLAMP or otherwise), and I got to cosplay from it with some of my favorite people; needless to say, I had a blast. Also I had giant mutton-chop sleeves. This came together pretty quickly, the skirt was thrifted and the jacket made from a modified pattern I already had, and it's actually super comfy. Just not for warm weather. The wig is a Chibi from Arda, twisted up into odongo buns and then attacked with a can of heavy duty hairspray.
