Halloween will be upon us sooner than we think, so it's time to start thinking about what to dress up as this year. Rather than wait till the last minute to put together a somewhat cohesive ensemble, let the stars do the work for you.

From the aggressiveness of Aries to the optimistic side of Sagittarians, every zodiac sign possesses a unique set of traits that embodies its personality. Here, check out which costume idea is perfect for your zodiac sign.

Aquarius: '60s Hippie

Aquarians are very progressive and creative individuals who love to fight for freedom and converse in deep, intellectual discussions with others. If this is your zodiac sign, your ideal costume this year would be based on someone who is independent and free-spirited, particularly a ’60s hippie.

Pisces: Mermaid

Although they can often be emotionally sensitive and overly trusting, Pisceans care deeply for those around them. As a water sign, Pisceans are very in tune with the ocean, so use your imagination to create a mesmerizing mermaid costume this year.

Aries: Warrior

An Aries is connected to the Greek god of war. Fierce, courageous, and ambitious, a warrior is an ideal choice to embody the traits of this fire sign.

Taurus: Cher

Those who fall under the Taurus zodiac sign are very reliable and devoted individuals who are committed to completing any tasks they’ve made for themselves. This year, choose someone like Cher who is strong-willed and enjoys wearing lavish garments.

Gemini: Clown

Geminis are always ready for fun. Those who belong to this social zodiac sign are extremely affectionate and curious individuals, so why not channel your energetic personality as a clown for Halloween? If you want a more specific costume idea, Harley Quinn has a variety of outfits you can wear that will complement your Gemini qualities.

Cancer: Ariana Grande

Cancers are highly imaginative and moody individuals who enjoy being comfortable whenever they can. For Halloween, Ariana Grande’s oversized hoodie outfits are a great option for those who want to stay warm and cozy all night.

Leo: Elton John

As natural-born leaders who are self-confident and usually dramatic, Leos love to be in the spotlight. There are many performers who knew how to make a statement, including Elton John with his eccentric costumes and lively personality.

Virgo: Beyoncé

What better celebrity for Virgos to embody this Halloween than the Virgo queen herself, Beyoncé? Virgos tend to be practical and well-organized individuals, so dress up in one of Beyoncé’s less elaborate outfits, such as her suit in her and Jay-Z’s “Apeshit” music video.

Libra: Goddess

The ruling planet of Libras is Venus, which makes those who fall underneath this sign very passionate and harmonious people who enjoy music, beautiful surroundings, and art. For Halloween, you can put together a costume that emulates the goddess of love herself.

Scorpio: Vampire

Scorpios are known for being passionate and resourceful people who can also become jealous, manipulative, or even violent. A vampire is a perfect costume idea that can be taken in many directions. Zoë Kravitz’s “Mornings Suck” vampire ensemble is one interpretation of this classic Halloween costume you can use as inspiration.

Sagittarius: Billie Eilish

Sagittarians are deeply curious people who love their freedom and independence. Choose someone to channel this Halloween that is known for speaking their mind, such as Billie Eilish. Bonus: Eilish is a fellow Sagittarian!

Capricorn: Stevie Nicks

Capricorns are grounded individuals who are independent but can also possess a more conservative side. Despite her bohemian style that gives off a sense of being free-spirited, Stevie Nicks can actually be quite modest at times. Her style is the perfect combination for someone who is down to earth but also powerful and driven.
