October 10, 2021

October is here, so it's officially spooky season! With Halloween rapidly approaching, it's now time to start thinking about what Halloween costumes to invest in this year. 2021 has brought a flurry of new trends while simultaneously reviving old ones, so there are plenty of ideas going around this year on what to wear. Here are some Halloween costume trends that will for sure be all the rage this year!

1. Scarlet Witch from WandaVision

The release of Marvel's WandaVision this year has, without a doubt, solidified the Scarlet Witch as one of the franchise's most beloved superheroes. The popular Disney+ series was a love letter to old sitcoms, traveling to a new decade with each episode, giving out plenty of outfits to choose from.

Whether you want to walk in the shoes of Wanda Maximoff's Sokovian fortune-teller Halloween costume, strut in the high heels of her 1950s housewife dress, or wear the new and improved Scarlet Witch superhero costume, there's an endless amount of outfits you can choose from.

2. Cruella De Vil from Cruella

Emma Stone's new Cruella film — the origin story of the iconic 101 Dalmatians villain — has rewritten the character to delve more into her fashionable roots. With this, there is a multitude of possibilities on how to dress up as the revamped villain! The movie, a practical homage to 1970s punk fashion, has endless outfits to choose from and is guaranteed to make you one of the coolest dressed in the room.

3. Harley Quinn from The Suicide Squad

This popular DC villain has taken over every Halloween costume department since her first arrival on the big screen five years ago. With the release of the newest Suicide Squad film this summer, the character isn't going away anytime soon. The movie has revamped her character in new ways, making her style more camp than ever. So why not participate in the Harley Quinn craze this year?

4. Olivia Rodrigo's “Good 4 U” Cheerleading Uniform

If there was one singer who dominated both the charts and pop culture this year, it's Olivia Rodrigo. The teen breakout star gained massive success from her single “Good 4 u”, an early 2000s time capsule reminiscent of the times of Paramore and teen breakup angst. One of her most regarded looks in the video, her donning a blue cheerleading outfit with black leather gloves, is practically her signature look — and is bound to bring out all the nostalgia this year.

5. Bella Swan from Twilight

The revival of Twilight has not only made Bella Swan trendy again, but made practically everything from the 2009 era trendy once more. The resurgence of Bella Swan-esque fashion has brought back a craze for henley sweaters, earthy tones, and low-rise jeans. With her style and the franchise already trending again, why not decide to dress up as Bella Swan?

6. A Loki Variant from Loki

Just like a lot of other movies and TV series on this list, the new Disney+ series Loki provides us with endless costume ideas for this year. It doesn't matter which Loki you want to dress up as — the original, Sylvie, or even President Loki — when October 31st arrives, there'll undoubtedly be plenty of Loki variants to go around walking the streets.

7. Dani Ardor from Midsommar

With A24's psychological horror movie trending on platforms such as TikTok once more — with people trying to mimic Florence Pugh's frown, and everyone gushing over Dani Ardor's flower dress — Midsommar has brought itself to be one of the most talked about horror movies this Halloween season. Dressing up as Dani Ardor in her flower dress is sure to be a trending costume this year.

8. Kim Kardashian's Met Gala Look

Out of all the Met Gala looks this year, Kim Kardashian's was one of the most talked about. The all black outfit, spanning from head to toe, made her resemble a “dementor” as tons of people had tweeted online. With online retailers already beginning to make Halloween costumes out of it, there's bound to be plenty sold this season.

9. A Grisha from Shadow and Bone

Dressing up as a Grisha from Netflix's newest YA fantasy series Shadow and Bone is practically the same as dressing up as Harry Potter years ago or Katniss Everdeen during the YA dystopia craze. Shadow and Bone is the newest in line of fantasy YA adaptations.

Whether you choose to dress up as main character and Sun Summoner Alina Starkov or one of the many magical Grisha throughout the show, you're bound to look stunning in your costume. And if you don't believe me, check out the beautiful Russian-inspired Keftas they wear in the show!

10. Black Widow or Yelena Belova from Black Widow

Yes, there is one last superhero addition to this list. Marvel's Black Widow film dropped this summer and, with that, also brought its heroine Natasha Romanoff back from the dead (well, almost), as well as introduced her sister, Yelena Belova. All you practically need is braided hair, smudged eyeliner and a vest with tons of pockets to easily dress up as either hero this Halloween.

11. A Player from Squid Game

Ever since Squid Game — Netflix's newest K-Drama — released this September, it gained enormous amounts of traction, and is on its way to becoming the service's most-watched series. With its release just in time for Halloween, there's bound to be many people dressed up in pink guard suits or the player's green tracksuits. With the costumes already being easy to put together, and the widespread popularity the show has massed, this idea is bound to be popular this year.

And that's all! Hopefully now you'll be filled with tons of ideas for Halloween costumes this year — the possibilities are limitless!
