The sisters' dress-up wings are made of polyester and polypropylene. They measure 45.5 x 16 cm and are fastened with elastic straps.

Anna and Clara are preparing for a dress-up party the nephew is holding at their house. He has invited some friends to join him on a fantastical adventure, so the sisters make sure there are plenty of costumes to choose from. "Do not forget the masks, dear Clara," Anna says, and she neatly displays costume pieces on hangers.
