Capricorns (Dec. 22 - Jan. 19) are characteristically practical, prudent, and ambitious. They have big dreams and take actionable steps to make them come true. For your costume this year, choose someone who had to work hard for her goals, like Tiana from Disney's "Princess and the Frog."

To make Tiana's princess dress from scratch, you'll need a gold tiara ($9, Walmart), and a green slip dress ($20, ASOS) layered over a longer cream colored slip dress ($12, Sears). For her waitress outfit, a yellow button-up collared dress ($16, Milanoo) with a white apron ($4, Open Tip) will do the trick.

Aquarius (Jan. 20 - Feb. 18) is known for its humanitarian spirit and artistic abilities. Those under this sign are often found pushing the envelope and developing new ways of doing things. What better example of each of those traits than Frida Kahlo herself?

Her costume is colorful, beautiful, and surprisingly easy to replicate. All you need is a flower crown ($13, Etsy), a white crop top or tee ($15, Milanoo), a floral maxi skirt ($40, American Eagle), and a colorful scarf ($22, Etsy) to drape around your shoulders. Don't forget to etch in a uni-brow with eyeliner to complete the look.

Pisces (Feb. 19 - March 20) are sensitive, creative, a bit on the wild side, and sympathetic. Marilyn Monroe was all of these things and, it turns out, is an iconic muse for Halloween.

All you need is a white, flowy dress ($30, JC Penny), some white heels ($21, Call It Spring), a curly blonde wig ($15, Target) — unless you're blessed with Monroe-esque curls already — and of course, bright red lipstick.

Aries (March 21-April 19) are fiercely independent, adventurous, and unafraid of blazing trails. They're confident and often considered dare devils. Rosie the Riveter is an iconic feminist, and who better to represent your self-confidence?

Her look is simple to recreate. Grab a chambray button up shirt ($25, American Eagle) and roll it up to your biceps. Throw on your favorite pair of jeans ($10, H&M) and pull your hair up with a red bandanna ($14, Levi's). Done and done.

Those under the Taurus sign (April 20-May 20) are reliable, leading, warm, and determined. They can also be possessive and very driven. Katniss Everdeen from The Hunger Games is a perfect example of a leader who possessed all of the qualities of a Taurus. Plus, her costume is so bad ass.

To dress like Katniss, wear a black tee ($6, H&M), with a black zip up jacket ($14, Rose Gal) over the top. On the bottom wear army green jeans ($9, H&M) and hiking boots ($55, DSW). Don't forget your dutch braid, bow and arrow ($10, Walmart) and, of course, the Mocking Jay pin ($4, Etsy).

Geminis (May 21 - June 20) are socialites who have great energy and a bubbly personality. However, they're also a bit cunning and divisive when they need to be. Just like Harley Quinn from Suicide Squad.

You can be as risque as you'd like for this costume, but the basics are her baseball style tee ($10, Discount Mugs) with "Daddy's Lil Monster" across the front (watch this tutorial to learn how to make it yourself), fishnet leggings ($7, Forever 21) with shorts over the top ($18, Forever 21) or black skinny jeans ($20, H&M). You can either dye your own hair (with that Gemini wild streak of yours), or buy a Harley Quinn wig ($25, Spirit Halloween).

Cancers (June 21 - July 22) are known for being protective, loving, overly emotional, and intuitive. Harry Potter's Molly Weasley is all of these things and more.

Molly's style is quirky, to put it lightly, so don't be afraid of pattern mixing and grabbing your costume entirely from a thrift store. You'll need a dark, partnered dress ($29, Simply Be), a cardigan or sweater ($20, Lands End), tights ($10, Old Navy), an apron ($4, JoAnns), and oxfords ($40, ASOS). If you can find a messy red wig, even better.

Leos (July 23 - Aug. 22) are known for their courage, and love of taking charge. Merida from Brave is the literal embodiment of those traits.

To dress as the Scottish lass, you'll need a long, green velvet dress ($19, Rose Wholesale), a brown belt ($17, H&M), boots ($40, JC Penny), a costume bow and arrow ($7, Spirit Halloween), and a curly red wig ($28, Cosplay Sky).

Virgos (Aug. 23 - Sept. 22) are a bit shy, and incredibly hard working. They're intellectual, reliable, and tend to be over achievers. Enter Hermione Granger.

Think layers with this costume. Start with a basic white button up shirt ($17, Kohls), add a grey cardigan ($30, Old Navy) and top it off with a long black jacket or coat ($88, Torrid). Wear black pants ($13, H&M) and don't forget your Gryffindor tie ($10, Party City).

Libras (Sept. 23 - Oct. 22) are diplomatic, proper, charming, and sociable, much like Marry Poppins herself.

You'll need your most proper attire for this costume: a white button up shirt ($12, Ali Express), ideally without a collar, a grey blazer ($17, Trends Gal), a black skirt ($27, She In), and a pair of flats ($13, H&M). Top off the look with a red bow tie ($6, Tie Mart), a boater hat ($30, Eloquii) and an umbrella ($7, Walmart).

Scorpios (Oct. 23 - Nov. 21) are powerful and passionate, they have magnetic personalities and can often get jealous and act out of resent, like Orange Is The New Black's Alex Vause.

To transform yourself into prison's most bad ass brunette, you'll need some tan scrubs ($9, Scrubs and Beyond), a white tee ($9, H&M), a pair of black glasses ($5, Eye Buy Direct), a black wig ($10, Rose Gal), and (if you want to be super thorough) a temporary rose tattoo ($1, UsImprints) for your arm.

Those under the Sagittarius sign (Nov. 22 - Dec. 21) are loyal, freedom loving, optimistic, and intellectual. Whether you're a Star Wars fan or not, Princess Leia is the perfect choice.

To make her outfit, you'll need a white, loose dress ($64, Torrid), a silver belt ($30, JC Penny), a fake gun ($14, Ebay), and her iconic braids, either as a wig ($13, Party City) or with your own hair.
