When Eleven (Millie Bobby Brown) visits Nancy’s room, a pink bottle can be seen on her chest of drawers. A pink bottle with a human face painted on it.
It’s Avon Miss Lollypop cologne mist, which here appears sans white hat. This fragrance for girls was launched in 1967: according to the reviews I’ve read, it was a gourmand perfume, smelling like candy.
