Bloomers were supposed to have vanished from P.E. classes since the turn of the milennium, and only appear in image clubs, cosplay groups, and 2D worlds! An endangered species of a costume that can't be found anymore!
Image Clubs are a kind of Japanese adult club in which the hostesses are dressed in costumes such as in aforementioned bloomers, or nurse outfits, etc.What a rare school Mitakihara Middle School is!!Oh!Sayaka spotted!...wait, that means this was Sayaka's class!Madoka and Homura are in it too!?
