Youth raincoat, Yoki brand, youth size 16

Yoki brand raincoat, youth size 16. My daughter never used it. I guess she thought she’d melt in the rain so just chose not to go out at all, raincoat or not. 🤷‍♀️ It does have a stain at the bottom; can’t imagine what from. She never actually used the coat & it never got wet.
