As reported several times, Kotobukiya Akihabara-kan is one of the major character toy/figure companies in Japan Kotobukiya's five-storey retail store in the Akihabara town, the mecca of otaku. The building has five floors: 1st floor is for anime goods; 2nd floor is for many kind of character goods; 3rd floor is "Hobby Floor" mainly focuses on model kits and pla-models; 4th floor is called "Show Room" for the newest samples and limited items from the company, and 5th floor "Kotobukiya Base Akiba" is for various events.
Between March 19 and 26 for one week, it was hoding a small exhibition featuring the school uniforms for the the Love, Chunibyo & Other Delusions anime series. It said those replica costumes were actually used in the events for the anime, probably worn by the anime voice actresses. As you can see below, they are not exactly same with the anime's visual, but still cute enough.
