People are sharing what they looked like at 15 years old compared to Millie Bobby Brown

The cast of Stranger Things lit up the red (or silver) carpet on Sunday night at the Screen Actors Guild Awards, with the Netflix drama nominated for three awards, including Outstanding Performance by a Stunt Ensemble in a Television Series.

Sadly, the cast walked away empty-handed, but that didn't stop the young stars looking like they were having a great time at the prestigious event.

However, one actor who grabbed more attention than the rest was 15-year-old Millie Bobby Brown, who wowed viewers in her white Louis Vuitton outfit.

Millie recently showed off her incredible singing skills during a vacation to the Turks and Caicos Islands:

Oozing glamor and class in her androgynous attire, people couldn't help but think that the teenager looked so mature for her age - leading to the star unintentionally sparking an online trend of people sharing that that looked like at 15 years old.

Here are some of our favorites:

I can 100% relate to this. I'm still annoyed at my mom for letting me leave the house with my hair dyed black and fingerless gloves.

Sadly, there were several people who felt like Brown's look was "inappropriate" for her age, calling for her stylists to be fired:

Twitter user Miranda Priestly’s Hair typed: "Millie Bobby Brown is 15 years old. Everyone who is responsible for this look needs to get fired".

And a Twitter user with the handle Janelle Belgrave L.Ac wrote: "She looks like she could be Natalie Portman or Celine Dion. I don't see a 15 year old here. She looks like she's an adult cast member crashing the teen photo."

Another user, Colette Browne, wrote: "Millie Bobby Brown’s stylist should sacked. She is just 15-years-old but looked at least 30 at the Sag awards last night. So disturbing."

Talking about her outfit in an interview with People, Brown said: "It’s everything I kind of wanted I definitely wanted to go for a masculine, but very feminine look - and they got it right as per usual."

The teenager then revealed that her life has changed "drastically" since bagging the role of Eleven on Stranger Things, explaining: "It’s changed drastically. It’s also been my forming years of being a teenager. I think I’m becoming stronger [...] It’s difficult because I’m still growing."
