A few American Girl collectors on Reddit got flyers with pictures of the holiday dress and other items for Holiday 2024, which is another collab with Janie and Jack, like what was done in 2022. This year's cranberry red, short-sleeved dress is a Janie and Jack item, and there will also be an embroidered black long-sleeve shirt, a sparkly white skirt, a pink long-sleeve shirt with black bows, and a black and white skirt. There will also be girl items to go with these outfits, and there could be more!
I'm not posting the images because I'm not sure if the flyers being mailed to these Reddit users was a mistake or intentional by American Girl, but American Girl's holiday releases are usually at the end of September or beginning of October, so we should expect these - and more - to be available soon!
