The Fairy Costume Accessories were introduced to Cécile and Marie-Grace's Collections in 2011 and retired in 2013. They are associated with the books Meet Marie-Grace and Meet Cécile. The complementary outfit was the Fancy Dress. Retail cost was $20.
- While an illustration in Meet Marie-Grace only shows Marie-Grace holding the mask and Meet Cécile shows no illustrations of the Fairy Costume Accessories, it can be seen in a promotional video.
- In Meet Cécile, Mademoiselle Océane describes the fairy costumes as left over from a children's production of the opera The Magic Flute.
