Stranger Things hit by wardrobe blunder

Stranger Things viewers were shocked after a major wardrobe blunder slipped under the radar when a garment featured from a company that was not yet established in the timeframe of the show.

The smash-hit Netflix series has been releasing its final season in batches - with the finale set to land on New Year's Day.

The moment featured Holly Wheeler (Nell Fisher), who became stuck in Vecna's (Jamie Campbell Bower) Pain Tree. As Holly tried to break free from this predicament, viewers noticed she appeared to be wearing a long-sleeve Under Armour T-shirt.

The popular sportswear brand launched in 1996, while Stranger Things' current storylines take place nine years earlier, in 1987.

Eagle-eyed fans were left asking 'How did Netflix not notice this?' after spotting the gaffe.

One viewer wrote on X: 'How does something like that even slip by?'

However, a second viewer defended the series, remarking: 'A mistake could happen anywhere, there is no need to dwell on it.'

It comes as the latest volume of episodes became available on Boxing Day - setting the stage for the final episode.

Meanwhile, showrunners Ross and Matt Duffer set the record straight on a 'confusing' moment featuring Jonathan Byers and Nancy Wheeler.

Viewers saw the couple share a tense and emotional moment in a dramatic, near-death scene.

Jonathan - portrayed by Charlie Heaton - pulled out an engagement ring in front of Nancy, who is played by Natalia Dyer.

The moment initially seemed like a proposal, however, the show's co-creators clarified that the couple are not engaged and explained their intent with the scene.

Off-screen, the actors who play Nancy and Jonathan are still a couple in real life, but their on-screen characters ended up breaking up during the romantic 'un-proposal' scene, the showrunners explained.

The pair are trapped inside the Hawkins lab in the Upside Down when a toxic, poisonous substance begins melting everything in the room.

Nancy then tells Jonathan that she hates The Clash. Then, he confesses that he doesn't like to read her articles and finally admits that he never applied to Emerson.

At that moment, he pulls out an engagement ring from his pocket and extends a proposal-like offer.

'I figure that I have screwed up enough with you that it'd be nice to get something right for once, in the end. Nancy Wheeler, will you not marry me?'

She accepts his 'un-proposal' before telling him she loves him and they kiss. After they part, they see the substance had hardened around them and realize they're still alive.
