These are the items in the Narue product lineup, as part of a collaboration between Sailor Moon and the Japanese department store company ISETAN to celebrate SM's 25th Anniversary!
The lineup features some super cute Sailor Moon and Sailor Chibi Moon-themed dresses, as well as other Sailor Moon themed accessories, including four different styles of slippers~
My personal favorites are the "Transformation Items Pattern Frill Puff Sleeve Dress" (second from the left in the picture), and the "Sailor Moon or Sailor Chibimoon Frill Puff Sleeve Dress"
You can check out Sailor Moon Collectibles for more info! Everything is so cute but definitely out of my price range, unfortunately ;^;
