With Stranger Things 2 having been released just days before Halloween, partygoers are gearing up to dress as their favourite characters from the Netflix show.

However, there’s been some controversy over one costume that’s been advertised online. Titled the ‘Upside Down Honey Costume’, the outfit resembles that of Eleven, one of the show’s leading and most beloved characters.

The costume comes with a pink dress, stockings, blue jacket, and fake Waffle purse. The model used to advertise the outfit also has a blood dripping from her nose, something that happens to Eleven during the series.

“Evade your enemies in this Upside Down Honey costume featuring a powder pink babydoll dress with a ruffled bust, white buttons accents, a navy bomber jacket with long sleeves, white thigh high socks with striped tops, and a waffle purse, reads the advert, adding: “(Wig not included.)”

Many fans of the show have expressed outrage online over the costume, calling out how the outfit makes a child character ‘sexy’.

“THIS. CHARACTER. IS. A. CHILD. What is wrong with these people?,” wrote one Tweeter.
