Amazon Naywig Cowgirl Outfit 

RRP: $49.99

This hot pink co-ord is a close match to the cowgirl look Margot Robbie sported in Barbie. Simply pair it with some boots and maybe a blonde wig and you're good to go!

It's a pretty safe bet that we're going to see endless iterations of Margot Robbie's roller-skating, patriarchy-busting Barbie this October 31, especially in her iconic Cowgirl get-up.

This outfit is an easy co-ord, that even without Barbie's blonde locks, will be a recognizable ode to the film.

2. 'The Little Mermaid'


Genuiskids Women's Mermaid Party Costume 

RRP: $14.78

This dress is the perfect easy mermaid costume! With just one simple, budget-friendly item, you've basically nailed Halloween—you don't even need to really bother with any other accessories! 

Disney's live-action remake of The Little Mermaid, starring Halle Bailey as Ariel sparked many a 'Mermaidcore'-related trend this year. So, no doubt you're likely already well equipped with some shimmering ocean-themed accessories for a mermaid look on the fly, or at the very least, you'll be able to find a costume pretty easily—thanks to all the buzz around the movie.

All you really need is a purple top or bralette and a sea-foam green skirt or pants for a really straightforward Ariel-inspired look. 

3. '13 Going on 30'

Is there anything more '00s than Jenna Rink's 13 going on 30 dress? Pair with some heels and am equally noughties-inspired updo and you're all set.

Put your hair in a messy bun, throw on a statement necklace and get into this multicolor dress. Boom! Jenna Rink! The striped design and cut-out feature will make you feel as though you've stepped back into 2004.

ZIW Women Wednesday Addams Dress

RRP: $28.99

This black skull-print dress with white accents at the collar pays homage to our icon, Wednesday—all you need is a black wig with bangs to finish off the look.

Wednesday Addams never goes out of style, no matter the generation of Addams you love (personally we can't wait for Wednesday season 2) and thanks to her affinity with monochromatic outfits, you need only throw on a black dress to embody her moody, gothic vibe.

5. 'IT'

ZHENWEI Rain Jacket Women: 

RRP: $39.99/£23.99

George's bright yellow raincoat is so iconic for spooky season. In fact, if you wear this to a Halloween party, few won't get the reference, especially if you pair it with a red balloon...

You'll be the best-dressed lady this side of the sewer with a bright-yellow raincoat à la Georgie. All you need is to pair this lightweight, zippered number with your favorite galoshes and you'll be mistaken for a resident of Derry, Maine. 

6. 'The Bachelorette'


Sparkly Bodycon Dress

RRP: $19.99/£16.99

For our reality TV lovers, a shimmery dress is an easy way to embody a Bachelorette.

A sparkly sequin number and a few red roses are all you need to channel your favorite reality TV show. Just make sure you hand out those florals accordingly, ladies. To dial up the spooky factor, pair it with one of these Halloween nail designs

7. 'Bridgerton'

Free People Selkie The Ritz Dress

RRP: $399

While Bridgerton Season 3 is still a while off, we can certainly channel the Regency-era drama for Halloween with a floaty number and a chic updo. It will also double as a dreamy occasion dress, so win-win!

We certainly hope you find the perfect costume that's all things spooky and comfy! If you need us, you can find us at the party next to the candy apples. We'll be the ones dressed like Pennywise's next meal.
