Lara Jean from To All The Boys I've Loved Before

• What to wear: Lara Jean has the cutest style. To achieve this look, wear a long, high ponytail with a pink ribbon bow, and pink outfit with a bomber jacket or cardigan. Keep makeup sweet and natural.

Rue From Euphoria

• What to wear: Rue has the laid-back style that everyone has tried to achieve at one point, and this Halloween [9] is the perfect time to channel the style of this Euphoria [10] favourite. Her vintage-inspired outfits consist of oversize cardigans, plenty of printed button-down shirts, and, most notably, her go-to Converse.

Jules From Euphoria

• What to wear: If you love Euphoria [11] as much as we do, being Jules for Halloween [12] is at the top of your list. While you could opt for one of her pastel-coloured babydoll tops with a pleated skirt and platforms sneakers, you could also try something a little more dangerous by dressing up as what she wore to the Halloween party. Her angel costume consisted of a long white dress, pronounced wings, and runny makeup.

Ashley O From Black Mirror

• What to wear: A lilac bob with shaggy bangs and a white crop top will do the trick for this Ashley O costume. Channel your inner superstar to make this look really come to life.

Sharon Tate From Once Upon a Time in Hollywood

• What to wear: If you want to be a total smokeshow for Halloween [13], we don't blame you. Take yourself back to 1969 by wearing go-go boots, a white skirt, and tight-fitting black turtleneck. Curl the ends of your hair in the most playful way, and put on the coy smile we know you have.

Sabrina and The Weird Sisters From Chilling Adventures of Sabrina

• What to wear: This could possibly be the most perfect Halloween [14] look, weather for one, for a trio of friends or a group of four. To channel your inner witch, you'll need a red dress, platinum bob, and a black alice band. If you're girls are going as the Weird Sisters then you'll need black dresses with Victorian-inspired contrasting white cuffs and collar. To really nail this look, have one girl with long black pigtails, another with a red braided crown, and the third with cropped blonde finger waves. Magic!

James, Michelle, Erin, Orla, and Clare From Derry Girls

• What to wear: Take yourself into the wild lives of these crazy teens this Halloween [15] by dressing up as one of the Derry Girls, James included. You'll need a green blazer, plaid skirt, black leather shoes, and whole lot of chaos to channel this group from an all-girls Catholic school in '90s-era Northern Ireland.

Eleven From Stranger Things

• What to wear: There are a few versions of Eleven you could be (Government Prisoner Elle, Hamburger-Eating Elle, Eggo-stealing Elle, etc.), but let's stick with the newest. A quirky patterned button up shirt that is tucked into black jeans is the way to go. Put suspenders across your body, and get in position! You know what pose we mean.

Robin From Stranger Things

• What to wear: Unless you want to be a total dingus, then you should definitely dress up as Robin from Stranger Things [16]. Her Scoops Ahoy outfit is the most notable, so we advise wearing a blue-and-white striped shirt with a navy vest and white collar on top.

Princess Jasmine From Aladdin

• What to wear: You'll want the finest jewels and tiaras in all the land for this Jasmine costume. Brightly coloured dresses, glittering accessories, and a desire for endless adventure will turn you into this timeless princess. Don't forget Rajah!

Villanelle From Killing Eve  

• What to wear: Villanelle's wardrobe is incredible from start to finish, but we recommend wearing an over-the-top, frilly dress complete with a (very) sharp knife. Slick your hair back in a ponytail, pop the Champagne, and whip up a batch of your best poison.

Veronica From Riverdale

• What to wear: Think updated Blair Waldorf. A tailored but flirty dress (i.e., plenty short), plus a string of pearls and heels.
• How to act: Classy, but like you also know how to have a good time. Find a redhead at the party and insist on calling him "Archie-kins."

Betty From Riverdale

• What to wear: A tight sweater with a white collared shirt underneath and jeans. Pull your hair back into a perky little pony and plaster a smile on your face. Bonus: you could be "Snake Dance Betty" and rock black, lacy lingerie underneath a baby blue button-down shirt and light pink skirt.

Josie From Riverdale

• What to wear: Go full kitty rock star with a leopard-print bodysuit, tail, and cat ears. You also obviously need a mic to belt it out.

Cheryl From Riverdale

• What to wear: A tight, black, off-the-shoulder crop top and choker, with a short plaid skirt and bright red lipstick. Finish it off with a long red wig if your hair isn't Cheryl's colour already!

Jughead From Riverdale

• What to wear: A dark t-shirt, an unbuttoned plaid shirt in darker tones, jeans, black boots, and a grey hat (that looks like a crown, preferably). If you're feeling creative, you can also wear a leather jacket with a snake stitched on the back.

Rey From Star Wars: Rise of the Skywalker

• What to wear: For this, you'll need a flowy white cape, white capri pants, and a tan leather belt. Wear dusty brown combat boots with fierce armbands and a slicked back bun. Oh, and don't forget the totally badass attitude.

Cult Members From Midsommar

• What to wear: And the flower headbands are back! The cult members from Midsommar paired these heavy duty bands with white flowy outfits, so we recommend the same.

Nadia From Russian Doll

• What to wear: If you've been feeling a little dead lately, embrace that feeling and channel all of the Nadia vibes you can. Wear an all-black outfit with tousled curls, and definitely carry around a cigarette.

Nakia From Black Panther

• What to wear: Nakia is always in shades of green, so go with an olive-toned dress that has a high neck, cutouts, and long sleeves. Also bring along a gold clutch full of secret spy trinkets from Wakanda. With the sequel [17] on the way, this costume couldn't be more perfect.

Shuri From From Avengers: Endgame

• What to wear: For this, you need fierce face paint, a pulled back bun, and her killer blue and black suit. Pair it with chunky combat boots and arm bands to really get in character.

Inmates From Orange Is the New Black

• What to wear: Regardless of which beloved character on the Netflix hit you decide to be, you'll probably need the same basic few things — a white t-shirt under an orange or khaki jumpsuit and plain slip-on shoes. Stick a name tag on your shirt if you want people to know which Litchfield inmate you are in particular, and make sure to add personal touches (Red = a white bandana around her bald spot, Taystee = always reading books, Alex = thick glasses).

Ruth aka Zoya the Destroya From GLOW

• What to wear: A metallic red, one-sleeved leotard with a black belt that has a gold star on the clasp. Tease your hair as high as it can go into a mohawk, of sorts, and wear dark lipstick and makeup.

Debbie aka Liberty Belle From GLOW

• What to wear: A white metallic leotard with red and blue glittery stars on the front, with some seriously teased blond curls.

Bernadette Fox From Where'd You Go, Bernadette

• What to wear: An incognito disguise will work well if you are dressing up as Bernadette from Where'd You Go, Bernadette. Wear large sunglasses with a light scarf and jacket, and complete your look with a chic bob.

Bo Peep From Toy Story 4

• What to wear: A classic and beloved character, Bo Peep is one of the cutest costumes out there. You'll need a baby blue jumpsuit with a violet shawl and big pink bow. Don't forget your shepherd's crook!

Detective Pikachu From Detective Pikachu

• What to wear: You'll want to find all the yellow clothing you can for this costume. Paint your cheeks with nice red dots and top it off with your favourite detective hat.

Lucy Stevens From Detective Pikachu

• What to wear: A red hoodie with black jeans and a pulled-back ponytail are the essentials for this Detective Pikachu costume. Wispy bangs and a determined 'tude will get you all the way.

The Tethered From Us

• What to wear: If you want to really scare people this Halloween [18], find a red jumpsuit, and get to it! Just beware, dressing up as the Tethered will bring out the worst in you.

Daenerys Targaryen From Game of Thrones

• What to wear: Long snow-white hair and tasteful Winter clothing will turn you into the beautiful Daenerys Targaryen in no time. Make sure to curl your long locks, and bring a dragon as your trusty accessory.

Cersei Lannister From Game of Thrones

• What to wear: For this costume, you can go with or without a tiara, but you must be sure to wear your most stern face and disapproving look. Opt for a velvet jacket with a turtleneck underneath, and if you can find some, add some light armor.

The Fab 5 From Queer Eye

• What to wear for Bobby: Bobby is a fan of short-sleeved button downs that have the sleeves rolled a little bit and are in a fun print. You can wear it with dark skinny jeans, and add in a utility belt to make it clear you're ready to build someone a house from scratch.
• What to wear for Karamo: Karamo pulls off white jeans like no other. Once you've got a great pair on hand, wear a denim shirt underneath a bomber jacket.
• What to wear for Tan: Tan is the fashion guru of the bunch, so you need to be looking on point. Wear a printed button-down shirt french-tucked into a pair of tastefully ripped skinny jeans, and pair with Stan Smith Adidas sneakers or boots.
• What to wear for Antoni: A graphic t-shirt of some kind with dark jeans, joggers, or even a pair of tan shorts. Antoni is also partial to cool sneakers. Maybe rock an apron to give your look an extra oomph.
• What to wear for Jonathan: Pull your long hair into a half-up, half-down style, and then you have a few options; casual Jonathan usually goes for t-shirts and skinny jeans with flip-flops, while his more fashionable looks are definitely daring. Don't be afraid of a plaid kilt paired with a tight black t-shirt, or even a pair of sock booties.

Forky From Toy Story 4

• What to wear: Think red, white, and blue if you're feeling like being Forky. You'll want to wear an all-white getup with red sleeves and perhaps blue lipstick. Creativity is key here.

Captain Marvel From Captain Marvel

• What to wear: To be the most powerful superhero ever, you'll need the iconic blue and red outfit as well as some insane superpowers. Lightly curl your hair and pair this outfit with red knee-high boots.

Agent H and Agent M From Men in Black: International

• What to wear: If you want to be as bad this team, you'll need to find a partner in crime and the most dangerous suit you can. To really get into character, you'll need to go cause mayhem on the streets.

Elton John From Rocketman

• What to wear: TBH, the crazier the outfit, the better. If you really want to dress up like the legend himself, you'll need circle sunglasses, a chic cowboy hat, and an outfit complete with colours and designs of all kinds. If you're really feeling wild, you can copy his devil outfit and go all out with feathers, flames, and sparkle, so much sparkle.

Queen Elizabeth II From The Crown

• What to wear: Since she has aged in season three, a conservative dress with, of course, dainty jewellery and a tasteful hairdo is best. Always add a touch of lipstick and pearls, too.

Molly and Amy From Booksmart

• What to wear for Molly: Pack on the plaid! A green plaid blazer with a bright yellow turtleneck will make you feel like nothing less than a smarty pants.
• What to wear for Amy: Remember when patches were cool? Well, they still are. Add patches to your favourite jean jacket, throw on a t-shirt, and give your outfit the finishing touch with a bandana. Done, done, and done.

Mantis From Avengers: Endgame

• What to wear: A pair of flesh-coloured antennae on your head, a black wig, and a metallic green minidress.

Bonnie Carlson From Big Little Lies

• What to wear: It's no lie that Bonnie is one of the most beautiful babes in Monterey, so why not channel some of her beauty and grace and be a part of the Monterey 5? To copy the disco outfit that she wore to Amabella's party, wear a crochet top, purple skirt, and loose-fitting disco-themed jacket. Don't forget the blue eyeshadow and red lipstick!

Madeline Martha Mackenzie From Big Little Lies

• What to wear: Small but mighty, Madeline Martha Mackenzie has killer style in Big Little Lies. Her disco diva outfit consisted of a pink windbreaker, sparkly shirt, and teased hair, so that costume idea is always fresh and fun. You could opt for one of her other looks by wearing a conservative but cute blazer with pants or a nice blouse with a tasteful skirt.

Celeste Wright From Big Little Lies

• What to wear: Looking like Celeste IRL would be the dream, but we can only hope. So, this Halloween [19] dress up as the goddess herself by wearing a killer disco dress and headband or opting for one of her classy yet sexy lawyer looks. Every Celeste look is a good look.

Jane Chapman From Big Little Lies

• What to wear: Shy and sweet with bangin' bangs, channelling your inner Jane Chapman shouldn't be too hard. Funky hippie clothing with lilac eyeshadow and a bold headband should do the trick. If you want to go for one of Jane's more basic outfits, simply wear a hoodie and headphones.

Buzz Lightyear From Toy Story 4

• What to wear: To infinity and beyond! We hate to tell you this, but you'll really need the whole costume to make this one realistic. Once you're in uniform, you can really shoot for the stars!

Woody From Toy Story 4

• What to wear: Giddy-up, partner! Get in the Toy Story 4 spirit by dressing up as everyone's favourite sheriff. You'll have to snag a yellow plaid shirt, cowhide vest, blue jeans, and a big ole cowboy hat.

Rick Dalton From Once Upon a Time in Hollywood

• What to wear: Smooth and sexy is the motto of this Rick Dalton outfit, and to pull it off, you need to be just that. A rich leather jacket, brown pants, and sweet style will take you right where you need to go.

Cliff Booth From Once Upon a Time in Hollywood

• What to wear: Blue jeans and a graphic tee are the main pieces to this puzzle. You might need some brown leather shoes and pilot shades to really give this outfit your all. Don't forget the bad boy attitude.

Genie From Aladdin

• What to wear: Big and blue is the motto of this costume! You'll want to paint your body with blue paint, accessorise to the max, and put your hair in a high braid on the top of your head. Now go make wishes come true!

Aladdin From Aladdin

• What to wear: Commoner clothes with big dreams and a genie lamp are all you need to be this Aladdin character. Complete this costume with a red vest over a loose-fitting t-shirt, and get ready to be taken to a whole new world.

Fleabag From Fleabag

• What to wear: Leave your filter at the door and throw on your favourite striped tee when you step into the character of Fleabag. This dry-witted woman keeps people on their toes, so be sure to do the same. If you want to make this into a couple's costume, dress your partner in a priest outfit, and you two are ready to take on the town!

Janet From The Good Place

• What to wear: The source of all information and knowledge within The Good Place, Janet knows how to dress. Wear a violet two-piece skirt set with a patterned blouse beneath, and consider yourself the best dressed artificial being out there.

Season 9 Cast From American Horror Story: 1984

• What to wear: The ninth season of the scary good show American Horror Story [20] is back, and this time with a gnarly '80s-themed cast. To dress up as one of them, blast back to the past and wear old school gym shorts, leopard print, and workout headbands. This costume will be totally radical, we promise.

The Belchers From Bob's Burgers

• What to wear for Louise: A green t-shirt dress, black Mary Jane shoes, and her signature pink bunny-eared hat.
• What to wear for Linda: A red, long-sleeved shirt with a pair of blue jeans and some red glasses. Don't forget a black wig with your ends curled out!
