Wonder nation size 3T girls woodland Pajamas with Fox and Owl picture

They are new with tags but my kids played next to them and got them a little dirty so they need a wash. On the back the left side and a little of the front left you can see some glitter play dough. I don’t know it it will wash out or not. They are still very cute and non flame resistant. They are girls toddler 3T. Ty
