Spa and Salon Set
Sleepover Set (which was out last year, but our Costco didn’t get this set.)
The costume accessories look like the ones from the Dress-Up Trunk available from American Girl. It looks like there are 2 separate packages, one with the doll and another with the trunk and costume. See American Girl online for better picture of the costume items. Each trunk is a different color.
Also they had Wellie Wisher Doll and Costume Sets. This is a 7 piece set includes Doll, trunk and costume accessory. There are only 3 dolls (Camille, Ashlyn and Willa).
Looking at the picture, Ashlyn’s costume is the butterfly wings, rainbow colored tulle skirt, butterfly head band, and flower wand wand entwined with ribbon . Looking at the picture, Camille’s costume is the rainbow colored tulle skirt, shell crown, shell, and shimmery seaweed skirt.
Looking at the picture, Willa’s costume is rainbow colored tulle skirt, felt owl mask, bright owl wings, and looks like the rose scepter.
