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.

This popular DC villain has taken over every Halloween costume department since her first arrival on the big screen five years ago.

So why not participate in the Harley Quinn craze this year?

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 resurgence of Bella Swan-esque fashion has brought back a craze for Ambercrombie 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?

Dressing up as the Grisha from Netflix's newest YA fantasy series Shadow and Bone is almost — and I mean almost, not completely — the same as dressing up as Harry Potter years ago during the fantasy novel craze or Katniss Everdeen during the YA dystopia phenomenon around 2012. 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 Kefta's they wear in the show!

10. Black Widow and 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

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 widespread popularity the show has massed, this idea is bound to be popular this year.
